How they work
ACT
Core mechanism: Psychological flexibility through acceptance, defusion, present-moment awareness, values clarification, and committed action
Ontology: Psychological inflexibility: cognitive fusion and experiential avoidance narrow behavioral repertoire
Buddhist Psychology / Contemplative Psychotherapy
Core mechanism: Sustained mindful investigation of the nature of mind reveals the constructed, impermanent nature of self and suffering (non-self/anatta); maitri (unconditional friendliness toward all experience) dissolves the aggression that maintains psychological suffering
Ontology: Suffering (dukkha) arises from the fundamental misapprehension of a permanent, solid self where none exists — clinging to this illusion and resisting impermanence generates the afflictive emotions (kleshas)

What each assumes — and misses
ACT
Philosophical roots: Pragmatism (James, Dewey — truth as workability); functional contextualism (Pepper); Buddhism (attachment as suffering, mindfulness); Skinner (radical behaviorism, reframed)
Blind spots: Acceptance framing can feel dismissive of legitimate suffering; metaphor-heavy approach may not land for all clients
Therapeutic voice: What if the goal isn't to get rid of the anxiety, but to take it with you toward what matters?
Buddhist Psychology / Contemplative Psychotherapy
Philosophical roots: Buddha (Four Noble Truths, Eightfold Path, dependent origination); Nagarjuna (emptiness/shunyata); Shantideva (compassion); Abhidharma (Buddhist phenomenological psychology); Trungpa (brilliant sanity, spiritual materialism); Merleau-Ponty (phenomenology — parallel project); William James (stream of consciousness); Varela (neurophenomenology, embodied mind)
Blind spots: Not manualized; unclear boundaries between therapy and spiritual practice; risk of spiritual bypass; cultural appropriation concerns; non-self doctrine can be destabilizing for fragile ego structures; no controlled research as psychotherapy
Therapeutic voice: Can you just sit with this suffering without trying to fix it? What happens when you stop resisting?
Choosing between them
ACT (Cognitive-Behavioral) and Buddhist Psychology / Contemplative Psychotherapy (Contemplative) come from different traditions, which means they assume different things about what a person is, what causes suffering, and what the therapeutic relationship is for. The choice between them is often less about "which works better" and more about which set of assumptions fits the client and the therapist.
