Domain XIV · Western esoteric, divinatory & new spiritual movements · Marquis de Puységur (Armand-Marie-Jacques de Chastenet) · 1784 · Buzancy, France

What it is

What it was. A historical healing practice, not a current school of therapy. Armand-Marie-Jacques de Chastenet, Marquis de Puységur (1751–1825), a French aristocrat and amateur scientist, attended Franz Anton Mesmer's teaching in Paris in 1784 and then tried animal magnetism on household staff,…

Format

• This is a historical practice, so the framework has two layers: (A) the course of treatment as Puységur documented it, so the therapist can recognise its echoes; (B) the psychotherapist's own work when a client encounters magnetism, mesmerism or somnambulist ideas today. Layer B is, built on the…
• Session elements as described: passes; the magnetiser's concentrated will and intention; attention to the patient's mental and emotional state and surroundings; directed imaginative activity; a clearly stated goal (Puységur held that vague intentions produced convulsions and disorganised action,…

Who practises it, and how they are trained or regulated

• "Mesmerism" trainings: workshops, online modules and hybrid courses (from a weekend to longer certifications) teaching low-verbal, gaze-based or touch-based inductions under the mesmerism label; some independent practitioners advertise "magnetic passes", "fascination" and "vital" energy work, one-to-one sessions, retreats and online videos. These usually do not invoke Puységur by name.
• Hypnosis trainings and literature: the word "somnambulism" survives in hypnosis teaching for a deep trance with amnesia; Puységur's text now reaches readers through the 2025 Routledge translation in a psychoanalytic-history series.

Evidence status, as the guide reports it

• Evidence status (one line). Mesmer's magnetic fluid was rejected by the two 1784 French commissions; the claimed thought-reading and clairvoyant faculties failed the one documented controlled test (1814), and modern magnetic "passes" have no identified biological basis or demonstrated effect; the…

Questions to explore with your client

• What drew you to it, and what are you hoping it will change?
• Is there physical contact? Was it explained beforehand, and do you feel free to say no or stop at any point?
• Does it involve any substance, plant preparation, remedy or supplement? Has your doctor or prescriber been told, especially about any medication you take?
• Does it involve fasting, a special diet or 'detox'? Have you discussed this with your doctor?
• Is it a group, retreat or community? How do they respond if someone wants to leave or raises a concern?
• Who runs it, and what training or registration do they hold?
• What actually happens in a session or meeting, and how often?
• What does it cost, and is there pressure to commit to more?
• How do you feel afterwards, in the hours and days that follow?
• Does it fit with, or clash with, the work we do here?

What practitioners of it watch for

• client disappointment; treat as material.
• the explanation being heard as dismissal of a valued experience; pair it with B1.
• referral felt as rejection. Working sign: the referral is taken up or knowingly declined.
• debt, secrecy, isolation from family, the practitioner as sole authority. Working sign: the client sets limits and keeps choices.
• derealisation persisting beyond the session; fear of the practitioner. Working sign: after-effects fade and the client feels in control.

When to involve someone else

• New or worsening physical symptoms, or advice to stop or change prescribed medication: involve the client's doctor or prescriber.
• Signs of coercion, isolation from family and friends, escalating costs or secrecy: discuss openly and consider safeguarding.
• A crisis or thoughts of suicide: follow your crisis protocol. In the US, call or text 988; in the UK and Ireland, Samaritans on 116 123.
