What it is

Big Mind (also "Big Mind Big Heart") is a guided dialogue process developed by Dennis Genpo Merzel (Genpo Roshi), a Zen teacher in the lineage of Taizan Maezumi Roshi and co-founder of the White Plum Asanga. It is not a psychotherapy. It is a spiritual training method that borrows the format of…

Format

• Big Mind is a framework of facilitated dialogue and retreat practice, not a phased treatment. Two frameworks matter: what the organisation offers, and the therapist's own work around it.
• The process: a facilitator-led dialogue moving from self-protective voices, through the Seeker and the Non-Seeking mind, to Big Mind and Big Heart and an integrated perspective. It can be done one-to-one, in small groups or in large workshops. The site also offers short self-guided versions lasting…

Who practises it, and how they are trained or regulated

• Relation to Zen practice: the organisation says Big Mind "does not replace traditional Zen training"; Genpo has called it "the third leg" of a stool alongside koan study and shikantaza (silent sitting).
• Version followed: the Big Mind process as Genpo Roshi's organisation describes it on bigmind.org (history, "Finding Your Big Mind", biography and retreat pages, 2025–2026 programme listings) and in the book listing for Big Mind Big Heart: Finding Your Way; Voice Dialogue as Hal Stone and Sidra Stone describe it (1994). The therapist procedures in sections 4B and 5 are clinical synthesis informed by case reports on…

Evidence status, as the guide reports it

• Evidence status (one line). No controlled outcome studies of the Big Mind process are known; claims of rapid awakening are self-reported by the founder and his organisation.

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; explore it as part of the work.
• Conflicting advice; keep the client at the centre of decisions.
• Family pressure that drives the participant closer to the group.
• A plan the client agrees to only to please you; check that they would really use it.
• Debt, hiding spending, or a sense that more giving brings more closeness to the teacher.

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.
