1. Introduction
Version followed: Pietro Ubaldi's own account of his "conscious inspirational mediumship" and evolutionary cosmology, as his Italian publisher (Edizioni Mediterranee) presents La Grande Sintesi and Le Noùri, and as Brazilian scholarship (A. M. Medeiros, 2022 and undated papers) and Brazilian Ubaldian study bodies present it. Brazilian Kardecist critiques are noted where they differ.
What it is. Pietro Ubaldi (born Foligno, Italy, 1886; died in Brazil, 1972) was an Italian writer described by scholars as a spiritualist philosopher, Christian and mystic. He wrote 24 volumes, the first nine published in Italy and the rest in Brazil, beginning with La Grande Sintesi (written 1932–1935) [source: Medeiros, Quaerentibus; Mediterranee, La Grande Sintesi; Ceccarelli 2024]. He taught in Gubbio and moved to Brazil in 1951, where his work is still read [source: Ceccarelli 2024; Medeiros, "Universalidade"]. This is not a therapy. It is a spiritual and philosophical current with study groups, publishers and seminars; this guide describes it as its sources present it, then sets out the psychotherapist's work with clients who hold it.
The mediumistic claim. Ubaldi described the source of his books as noúri (Italian noùri; Portuguese noúres), which he described as "currents of thought" (from Greek nous, mind, and rheo, to flow). He called the source of his "Great Messages" (from 1931) "His Voice" (Sua Voce / Sua Voz) and said it should not be pictured as an individual person or spirit [source: Medeiros 2022, ABHR]. He called his gift "mediunidade inspirativa consciente": the receiver stays awake, chooses and actively seeks the current, and receives it through resonance and affinity (sintonização; Italian "sintonia d'onda") [source: Medeiros 2022; Mediterranee, Le Noùri]. His publisher states that he held the noùri to be the harmonious emanation of God's infinite thought [source: Mediterranee, La Grande Sintesi].
The cosmology. The universe is presented as a single, vibrating image of God governed by one inescapable evolutionary law. Matter, energy and spirit are three modes of one substance, and evolution moves from matter through energy to spirit, converging on God as "omega". Life ascends through mineral, plant, animal and human forms, and consciousness then continues to evolve through successive lives [source: Mediterranee, La Grande Sintesi; Medeiros, Quaerentibus; Medeiros 2022, RBFR]. Later volumes include The System (Genesis and Structure of the Universe) and Fall and Salvation [source: Wikipedia list of works; uncertain: secondary, unverified]. A Kardecist critic states that Ubaldi, like J.-B. Roustaing, taught a "Spiritual Fall" of spirits that precedes evolution, and that this conflicts with Kardec's view of reincarnation [source: Moreira 2014]. The detailed structure of the fall and of the paired "System / Anti-System" is [uncertain: not verified].
How change happens, in its own terms. Change is spiritual evolution: the person's consciousness rises from sensory to rational, intuitive and finally mystical-unitary awareness, "no longer by intellect alone but by love" (paraphrased from the Portuguese) [source: Medeiros 2022, RBFR]. Mediumship itself is said to evolve, so that in the future every person may be normally mediumistic [source: Medeiros 2022, ABHR]. The ethical programme is love of neighbour, universality and impartiality across religions [source: Medeiros, "Universalidade"].
Relation to Spiritism and the Church. Scholarship states that Ubaldi's work is not a Spiritist work but was widely received in Brazilian Spiritism because of shared themes: evolution, reincarnation, survival and communication with invisible beings. In 1951 he met the medium Chico Xavier, and both reportedly produced simultaneous messages [source: Medeiros 2022, ABHR]. Some Kardecist writers reject his work as schismatic and say he never considered himself a Spiritist [source: Moreira 2014]. A popular Italian article reports that his books were placed on the Catholic Index and later readmitted [source: Ceccarelli 2024; uncertain: not verified].
Evidence status (one line). The claim that the texts come from a divine or spiritual thought-current is a faith claim and has not been tested empirically [synthesis]; a physicist's analysis of A Grande Síntese reports significant errors in its physics [source: Fonseca 2014].
2. Framework
Two frameworks are involved: the current's own path, and the clinician's.
The current's path (as its sources describe it).
- Study: reading the 24 volumes, usually starting with A Grande Síntese and the "Great Messages"; study groups and associations in Brazil and Ubaldian study centres in Foligno, Italy [source: Medeiros, "Universalidade"; Ceccarelli 2024]. The Brazilian association founded in Campos (RJ) in 1949 as the Associação Brasileira dos Amigos de Pietro Ubaldi was renamed, at Ubaldi's request, Associação Brasileira da Universalidade de Cristo (ABUC), so that "the idea" would come before any personality [source: Medeiros, "Universalidade"]. Publishing bodies include the Fundação Pietro Ubaldi, the Instituto Pietro Ubaldi and the Fraternidade Francisco de Assis (Campos dos Goytacazes) [source: Medeiros 2022, ABHR and RBFR].
- Public seminars: for example, a Brasília seminar on "Pietro Ubaldi and the New Age" run by the Instituto Chico Xavier at its Monte Alverne site: lectures, a reading of one Great Message from a recording, and a round table, with free registration and a live broadcast [source: Correio Braziliense 2022].
- Ethical and mystical life: love of neighbour, tolerance and impartiality; the mystical ascent described in Ascese Mística [source: Medeiros, "Universalidade"; Medeiros 2022, RBFR].
- Inspirational receptivity: Ubaldi's books describe how he received the noùri. His publisher says Le Noùri explains his methods and links paranormal capacity to purifying body and senses, but the methods are not spelled out in public summaries [source: Mediterranee, Le Noùri]. Ubaldi did not seek followers or power, according to Medeiros [source: Medeiros, "Universalidade"]. Grades, initiations or membership fees: none found in the sources consulted.
The clinician's framework (synthesis). No session count or duration is given in any source; pace by need [synthesis].
- Engagement and meaning (first sessions): learn what Ubaldi's work means to the client, in the client's words. Move on when the client feels the belief is respected and you both understand its role in the presenting problem.
- Cultural formulation and assessment: Cultural Formulation Interview with its spirituality, religion and moral traditions supplementary module; screen for distress, impairment and loss of control linked to any inspirational or mediumistic experiences, and for depression, psychosis, mania, dissociation, OCD and complicated grief. Move on when you have a working formulation that separates the belief system (not a target) from any symptoms or problems (targets).
- Problem-focused work: standard evidence-based treatment for the disorder or problem found, adapted to the client's framework (for example, using the current's own themes of love, tolerance and growth as values), and work on specific difficulties such as guilt and suffering, doctrinal conflict, or overwhelming experiences.
- Consolidation and referral/liaison: relapse planning; with consent, liaison with the client's study group or Spiritist centre; referral where needed (psychiatry for psychosis or mania; specialist services for dissociation).
3. Guiding principles
- Describe, do not adjudicate. The noùri, "His Voice", the fall and spiritual evolution are the client's beliefs; neither confirm nor dismiss them. In practice: use the client's terms with a short gloss and never argue cosmology [synthesis].
- Belief is not a symptom. Holding an unusual cosmology or reporting inspiration fits a recognised religious tradition in Brazil. In practice: assess distress, impairment, control and course, not content [source: Menezes, Alminhana and Moreira-Almeida 2012].
- Distress and loss of control are the key signals. In practice: when experiences frighten the client, cannot be stopped, or disrupt work and relationships, evaluate further [source: Menezes et al. 2012].
- Meaning frameworks can protect. Distress may come from lacking a framework for unusual experiences. In practice: help the client make sense of experiences in their own tradition before reaching for diagnostic labels [source: Menezes et al. 2012].
- Use the current's own values as resources. Ubaldi's programme stresses love of neighbour, tolerance, impartiality and honesty over religious labels. In practice: invoke these when working on conflict, shame or exclusivist pressure [source: Medeiros, "Universalidade"; synthesis].
- Name the version. Ubaldian, Kardecist and Roustaingist readings differ and conflict. In practice: ask which reading the client and their group hold; do not assume Spiritist orthodoxy [source: Moreira 2014; Medeiros 2022].
- The therapist is not a medium or teacher. In practice: no readings, channelled guidance, or interpretation of messages for the client; refer doctrinal questions to the client's community [synthesis].
- Consent and client lead. In practice: raise spirituality only with permission, and let the client decide how far it enters therapy [synthesis].
- Watch power and money, without presuming them. In practice: ask about costs, pressure and leadership; exploitation by Ubaldian bodies: none found in the sources consulted.
- Competence. Spiritual and religious competencies for psychologists (Vieten et al. 2013) apply [source: Vieten et al. 2013; uncertain: not verified].
4. Intervention inventory
Part A outlines the practices of the current as its sources describe them, so the clinician knows what the client is doing. Part B gives the clinician's interventions. The therapist does not lead any Part A practice in session.
Part A. Practices of the current (public outline)
A1. Study of the works and study groups
- Purpose / when it appears: the core activity of Ubaldian circles: reading the 24 volumes, beginning with La Grande Sintesi (Portuguese A Grande Síntese), to understand the evolutionary law and live by it [source: Mediterranee, La Grande Sintesi; Medeiros, "Universalidade"].
- Outline: individual reading and group study in associations such as ABUC (Campos, RJ), Spiritist centres that read Ubaldi, and study centres in Foligno; Brazilian editions from the Instituto Pietro Ubaldi, the Fundação Pietro Ubaldi and the Fraternidade Francisco de Assis [source: Medeiros 2022; Medeiros, "Universalidade"; Ceccarelli 2024].
- Example language (illustrative): "What draws you to these books? What do you take from them into your week?"
- Watch for: study used to make sense of life and to belong (often protective); versus obsessive re-reading for certainty, or isolation from family over doctrine [synthesis].
A2. Reading the "Great Messages"
- Purpose / when it appears: short devotional texts Ubaldi said were dictated by "His Voice", beginning with the Christmas Message of 1931; read aloud at seminars, sometimes from a recording [source: Medeiros 2022, ABHR; Medeiros, "Universalidade"; Correio Braziliense 2022].
- Outline: a reading in a gathering, followed by lectures or discussion [source: Correio Braziliense 2022].
- Example language (illustrative): "When you hear the message read, what happens for you?"
- Watch for: comfort, hope, sense of mission; versus a client who feels personally addressed and commanded by the text in ways that override judgement, which needs gentle assessment (B4) [synthesis].
A3. Conscious inspirational receptivity (noùri)
- Purpose / when it appears: Ubaldi's model of how insight arrives: a fully awake person "tunes in" by affinity to a current of thought, receiving rather than being possessed, and keeps choosing and investigating [source: Medeiros 2022, ABHR; Mediterranee, Le Noùri]. Some readers try to cultivate this.
- Outline only: Ubaldi described a spiritual centre that he likened to a sun, contacted by "wave attunement", and linked receptivity to purifying body and senses; his methods are set out in Le Noùri and are not reproduced here [source: Mediterranee, Le Noùri]. Ubaldi held that mediumship develops through evolution and that, in future, every person may be normally mediumistic [source: Medeiros 2022, ABHR]. Any purification practices involving food, sleep or bodily austerity are not described here; if a client reports restricting food or sleep, assess medically.
- Example language (illustrative): "When ideas come to you this way, how does it feel? Are you in charge of when it starts and stops?"
- Watch for: writing or insight the client can start and stop, which leaves daily life intact; versus voices, compelled writing, loss of time, grandiose mission, or sleeplessness (B4) [source: Menezes et al. 2012; synthesis]. Channelled material that produces "recovered" memories of abuse or past lives: see Domain VI 110 on suggestion and false memory.
A4. The ethic of universality, impartiality and love of neighbour
- Purpose / when it appears: the moral programme of ABUC: love of neighbour regardless of religion, nation, race or culture (including atheists), honesty above labels, tolerance that seeks common ground, and rejection of claims to exclusive truth [source: Medeiros, "Universalidade"].
- Outline: practised in daily conduct and taught in study groups [source: Medeiros, "Universalidade"].
- Example language (illustrative): "You've told me Ubaldi asks people to look for common ground. How might that apply to the argument with your brother?"
- Watch for: a resource for values-based work (B6); or self-criticism when the client cannot live up to it (B5) [synthesis].
A5. The mystical ascent
- Purpose / when it appears: the path described in Ascese Mística: consciousness passes from sensory to rational-analytic, intuitive-synthetic and mystical-unitary levels, with ascent by love and through union with Christ's passion [source: Medeiros 2022, RBFR].
- Outline only: contemplative and devotional life within the client's Christian frame; no techniques are given here.
- Example language (illustrative): "Where would you place yourself on that path right now, and how would you know you'd moved?"
- Watch for: growth, compassion and steadiness; versus suffering idealised as necessary for ascent so that the client tolerates harm or neglects treatment (B5) [synthesis].
Part B. The psychotherapist's interventions
B1. Client-led exploration of meaning
- Purpose / when to use: from the first session whenever the client mentions Ubaldi, noùri, Spiritism or spiritual evolution.
- Steps: (1) Ask permission to talk about it. (2) Ask the client to explain the ideas in their own words; note their terms (noùri, "His Voice", the fall, evolution, the System). (3) Ask what role the ideas play: comfort, explanation of suffering, community, mission. (4) Ask how the ideas bear on the presenting problem. (5) Reflect back in the client's terms and check accuracy [synthesis].
- Example language (illustrative): "I'm not an expert in Ubaldi's work. Would you teach me the parts that matter most to you?" / "How does this way of seeing the universe help you with what brought you here? Does any part of it make things harder?"
- Watch for / working: the client relaxes, uses their own vocabulary freely, and links beliefs to concerns. Not working: the client tests whether you think they are "crazy"; name your stance explicitly [synthesis].
B2. Cultural Formulation Interview, with the spirituality, religion and moral traditions module
- Purpose / when to use: early assessment, especially where symptoms and beliefs intertwine or the client is in a Brazilian or Italian Spiritist or Catholic setting [source: DSM-5-TR CFI; uncertain: not verified].
- Steps: (1) Use the core CFI to elicit the client's definition of the problem, cultural explanations, supports and stressors, and expectations of help. (2) Add the supplementary module to map affiliation (Ubaldian, Kardecist, Roustaingist, Catholic, mixed), practices (A1–A5), the role of spirituality in coping, and any spiritual conflicts. (3) Ask how the client's group would understand the problem and what it would advise. (4) Record the formulation in the client's terms [source: DSM-5-TR CFI; uncertain: not verified; synthesis].
- Example language (illustrative): "How would people in your study group explain what's been happening to you?" / "Has your spiritual life helped with this, or made it harder?"
- Watch for: discrepancies between the client's and the group's explanation; family members who see the practice differently. Where religious or spiritual distress is the focus and no disorder is present, consider Religious or Spiritual Problem, Z65.8 [source: ICD-10-CM Z65.8 (Unbound Medicine)]; DSM-5-TR wording [uncertain: not verified].
B3. Engaging the client's community, if the client wishes
- Purpose / when to use: where the study group or Spiritist centre is a support, or where doctrinal questions arise that a therapist should not answer.
- Steps: (1) Ask whether the client would like contact with a group leader. (2) Obtain written consent and agree what may be shared. (3) Keep the focus on support and safety, not doctrine. (4) Review with the client afterwards [source: Menezes et al. 2012 on religious settings as a resource, coordinated with mental-health professionals; synthesis].
- Example language (illustrative): "Would it help if I spoke with someone from your group about how they can support you this month? You decide what I share."
- Watch for: the group supports treatment; versus pressure to replace treatment with spiritual work, which needs a direct conversation about safety [synthesis].
B4. Differential assessment of inspirational and mediumistic experiences
- Purpose / when to use: when a client reports receiving thought-currents, voices, messages, automatic or inspired writing, or a sense of mission.
- Steps: (1) Describe the experience concretely: onset, frequency, duration, content, context. (2) Rate against suggestive criteria for non-pathological experiences: little distress; no impairment or separate disorder; brief and episodic; some critical distance; fit with a cultural or religious tradition; controllability; promotes growth; oriented to others [source: Menezes, Alminhana and Moreira-Almeida 2012]. Note these criteria are indicators awaiting validation, not a test. (3) Separate recent-onset from long-standing, integrated experiences [source: Menezes et al. 2012]. (4) Screen for psychosis (thought disorder, persecutory or bizarre beliefs beyond the tradition, functional decline), mania (reduced need for sleep, pressured writing, grandiose mission), dissociation (amnesia, loss of time, identity disturbance), OCD (intrusive, unwanted religious thoughts with neutralising) and complicated grief (seeking messages from the dead). (5) Ask the group's view: do co-believers see the experience as typical? (6) Refer urgently for psychiatric assessment if there is risk, rapid decline or mania [synthesis].
- Example language (illustrative): "Ubaldi wrote that he stayed fully awake and in charge when ideas came. Is that how it is for you, or does it sometimes take over?" / "Has your sleep changed since the messages started?"
- Watch for: distress and loss of control are the most clinically relevant signals [source: Menezes et al. 2012]. Do not treat the content of the belief as evidence of illness.
B5. Working with suffering, guilt and the fall narrative
- Purpose / when to use: when the client uses the fall, evolution or karmic ideas to explain illness, loss or abuse in ways that drive shame, self-blame or passive endurance. The current itself treats pain within the "logic of destiny" (title of a 2022 seminar lecture) [source: Correio Braziliense 2022]; details of Ubaldi's teaching on pain are [uncertain: not verified].
- Steps: (1) Explore what the client believes their suffering means. (2) Distinguish the client's chosen meaning from self-punishment. (3) Ask whether the tradition also offers mercy, love and growth (it stresses love of neighbour and ascent by love) [source: Medeiros, "Universalidade"; Medeiros 2022, RBFR]. (4) Use standard cognitive or compassion-focused methods on self-blame, without disputing doctrine. (5) Check that the meaning does not lead to tolerating abuse or refusing care [synthesis].
- Example language (illustrative): "You see this illness as part of your evolution. Does seeing it that way also mean you have to face it without help?" / "If a friend in your study group were going through this, what would Ubaldi's ethic of love ask you to tell them?"
- Watch for: reduced shame, help-seeking; scrupulosity (repetitive moral checking, fear of 'falling back') suggests OCD and calls for ERP adapted with religious sensitivity as IOCDF describes [uncertain: not verified; synthesis].
B6. Values-based use of the current's ethic
- Purpose / when to use: conflict with family over beliefs, interfaith marriages, isolation.
- Steps: (1) Elicit the values the client draws from Ubaldi (universality, impartiality, tolerance, honesty) [source: Medeiros, "Universalidade"]. (2) Link them to concrete behaviours in the problem area. (3) Plan small actions. (4) Review [synthesis].
- Example language (illustrative): "If impartiality means not taking sides but understanding all, what would one step towards your mother look like?"
- Watch for: greater flexibility; or the ethic used as a weapon in arguments [synthesis].
B7. Doctrinal conflict and identity within Spiritist circles
- Purpose / when to use: distress from disputes between Ubaldian, Roustaingist and Kardecist readings, or rejection by a centre that sees Ubaldi's work as schismatic [source: Moreira 2014].
- Steps: (1) Validate the loss of belonging. (2) Explore the client's own position, without taking a doctrinal side. (3) Map supports in and outside the community. (4) Work on grief for lost relationships if needed [synthesis].
- Example language (illustrative): "It sounds painful to be told your reading is wrong by people you trusted. What do you want to keep from that community?"
- Watch for: isolation, depression; respect the client's choice to stay, change groups or leave [synthesis]. See also 100 (Kardecist Spiritism) and 098 (mediumship development circles).
B8. Grief and seeking contact with the dead
- Purpose / when to use: bereaved clients drawn to Ubaldi or to Spiritist mediums (Ubaldi lost two children during the Second World War [source: Wikipedia; uncertain: secondary, unverified]).
- Steps: (1) Explore the bond with the deceased and how the client's cosmology frames it (survival, continuing evolution). (2) Support continuing-bonds work that fits the belief. (3) Screen for prolonged grief and for paid-medium dependence. (4) Treat prolonged grief with standard approaches [synthesis].
- Example language (illustrative): "In your understanding, your son continues to evolve. How do you stay connected to him in your everyday life?"
- Watch for: comfort and gradual re-engagement with life; versus escalating paid consultations or inability to function [synthesis].
B9. Dependency, money and leadership check
- Purpose / when to use: routinely, briefly, and whenever the client's time, money or decisions seem controlled by a group or teacher.
- Steps: (1) Ask about costs (books, courses, donations) and who decides. (2) Ask about pressure to cut off outsiders, give up treatment, or obey messages. (3) Note that the sources here describe free public seminars and Ubaldi's own wish that "the idea" come before any personality [source: Correio Braziliense 2022; Medeiros, "Universalidade"]. Exploitation by Ubaldian bodies: none found in the sources consulted. (4) If coercive control appears in a particular group, use the general approach to high-control groups in this domain [synthesis].
- Example language (illustrative): "Some groups are easy to come and go from, and some aren't. How is it with yours?"
- Watch for: freedom to question and leave = low concern [synthesis].
B10. Children and safeguarding
- Purpose / when to use: a child is involved in mediumistic practice, or a belief is used in place of medical or developmental assessment.
- Steps: follow local safeguarding procedures; support referral for medical, ADHD or autism assessment; obtain consent from parents and assent from the child [synthesis].
- Example language (illustrative): "Your faith matters here, and so does making sure a doctor sees her. Can we plan both?"
- Watch for: refusal of necessary care, which triggers safeguarding duties [synthesis].
5. Handling problems
The sources on Ubaldi address doctrine, not therapy; all guidance below is [synthesis] unless a source is named.
- Client fears being judged as mentally ill. Say plainly that you will not treat their beliefs as symptoms and that you assess distress and functioning, not faith [source: Menezes et al. 2012 for the criteria]. Illustrative: "Many people in Brazil and Italy read Ubaldi. My job is to help with what's hurting, not to rule on the universe."
- Client asks the therapist to interpret a message or confirm that it came from the noùri. Decline warmly and return to meaning and effect; offer the community (B3) for doctrinal questions. Illustrative: "I can't say where it came from. I can help you notice what it's asking of you and whether that's good for you."
- Overwhelming or uncontrollable inspirational experiences. Shift to stabilisation: sleep, routine, grounding, reduced solitary practice by the client's own choice; assess for mania, psychosis and dissociation (B4); refer urgently if there is risk. Do not teach or coach any receptive practice.
- Grandiose mission or rapid escalation (writing through the night, new revelations, spending). Treat as possible mania until assessed; involve psychiatry and, with consent, family.
- Stuck in self-blame through the fall or karmic narrative. Use B5; look for the tradition's own resources of love and growth; consider whether scrupulosity (OCD) is driving it.
- Refusal or delay of medical care on spiritual grounds. State the risk directly, keep the alliance, and route health decisions to the client's doctors; never advise on medicines. Safeguarding duties apply for children (B10).
- Doctrinal disputes cause rupture (for example, the therapist is perceived as siding with a Catholic or Kardecist view). Acknowledge, repair, and restate neutrality. Illustrative: "I may have sounded as if I had an opinion on which reading is right. I don't, and I'm sorry if it felt that way."
- Non-adherence to therapy tasks because study or devotion comes first. Integrate: link tasks to the client's values (B6) and schedule around practice.
- Family members alarmed by the client's beliefs. With consent, offer a family session focused on behaviour and wellbeing, not doctrine; separate concern about belief from concern about functioning.
- Client wants to leave a group, or has been rejected by one. Use B7; support grief and rebuilding of community; avoid steering the decision.
- Bereaved client seeking messages from the deceased. Use B8; check for paid-medium dependence and prolonged grief; continuing bonds can be supported within the client's framework.
- Recovered memories or past-life material arising from channelled writing. Do not use them as evidence of events; address suggestion and false memory (see Domain VI 110).
- Therapist's own beliefs. If you share or oppose the current, consider supervision; keep any personal spiritual practice separate from therapy; self-disclose only for the client's benefit.
