The substrate.

John's own lineage. Almost no app does this well. Strong v1 candidate for first-class treatment given relational and affective focus.

Substrate for the product. Parts-as-creatures model. Default lens for new users.

Foundation for safe nervous system work. Cross-prerequisite for IFS exile work.

Hindu nondual lineage. Ramana, Nisargadatta. Atmavichara — self-inquiry — is the spine.

Heart-centered devotional path. Kirtan, japa, surrender. Strong sonic and relational.

Clinical mainstream. Provides legitimacy and crossover. Limited channel coverage but high efficacy in its domain.

Lectio, centering prayer, examen lineage. Important for users with Christian background who otherwise feel excluded from contemplative apps.

Strong channel spread for a clinical tradition. Useful for high-effort tier users. Skills are well-codified and teachable.

Mindful body-based psychotherapy. Bridges SE and IFS — strong somatic, affective, relational.

Jesus Prayer, prayer of the heart, monastic stillness. Fills the Eastern Christian gap.

Jewish mystical lineage. Kavanah, hitbodedut, sephirot. Letter mysticism and niggun.

Kabat-Zinn's secular adaptation. Bridges Vipassana with CBT/DBT cluster. Clinically validated.

Pure cognitive lineage. Useful for users who need a non-spiritual frame. Same skill substrate as CBT in many ways.

Heart-centered tradition. Strongly affective and relational. Beautiful poetry as integration.

Only tradition with strong Natural channel emphasis. Important for the ecosystem metaphor's coherence.

Full-spectrum tradition. Heaviest entry. Requires careful authorship — many practices are traditionally only taught with empowerment.

Accessible Buddhist lens. Good v2 first lens addition.

Strong somatic and sonic emphasis. Eight-limb structure aligns naturally with tier progression.

Strong somatic-cognitive integration. Koan work is unique among traditions.
