CH01: What Is Dependent Origination (Paṭicca-samuppāda)

At-a-glance: Foundations • Map & Scope

A. Definition & place in DO

• Paṭicca-samuppāda = “dependent-on-conditions, well-arising”: when this is, that is; with the arising of this, that arises; when this is not, that is not; with the cessation of this, that ceases (SN 12.1).

• The twelve links (forward chain): avijjā → saṅkhārā → viññāṇa → nāma-rūpa → saḷāyatana → phassa → vedanā → taṇhā → upādāna → bhava → jāti → jarāmaraṇa (SN 12.1).

• Cessation: with the cessation of avijjā, saṅkhārā cease … thus dukkha ceases (SN 12.1).

• No first cause: saṁsāra is beginningless; avijjā is not “the first event,” though it functions as a root in this analysis (SN 12.1–12.2).

• Mogok framing: the map is read across four layers/periods—Past Cause, Present Effect, Present Cause, Future Effect—while keeping exactly 12 links.

• Two roots (mūla) emphasized for practice: past-cause avijjā and present-cause taṇhā.

• Three rounds (vaṭṭa): Kilesa (defilement), Kamma (action), Vipāka (result) flow through the chain; seeing their hand-off points clarifies practice.

• Practice pivot: in daily life, the hot spot is phassa → vedanā → taṇhā—catch craving as it tries to form.

B. Mechanism (how conditionality works)

• Conditioned arising: Each link is necessary but not sole—given the right set of conditions, the next link tends to arise (e.g., with contact, feeling; with feeling, craving).

• Bidirectional reading: We study both arising (anuloma) and cessation (paṭiloma); classroom work alternates between these to strengthen understanding.

• Rounds in motion:

  • Kilesa-vaṭṭa: ignorance & craving bias perception and intention.

  • Kamma-vaṭṭa: intentions (saṅkhārā) build actions & habits.

  • Vipāka-vaṭṭa: results are experienced as consciousness, name-&-form, six bases, contact, feeling.

• Mogok three connections (signposts for teaching):

  1. Saṅkhāra → Viññāṇa (kamma→result hand-off),

  2. Vedanā → Taṇhā (moment-to-moment tipping point),

  3. Bhava → Jāti (kamma-becoming conditioning birth/result).

C. Practice (quick drills, 1–3 minutes)

1. One-minute map read-through
   Whisper the twelve links in order (Pāli) twice; on the third pass, add the three connections out loud. Aim for smooth, unbroken sequencing.

2. Vedanā checkpoint
   Sit or stand; let a small stimulus happen (sound/itch/thought). Label phassa → vedanā. Ask, “What is the urge?” Name it as taṇhā or “none.” Relax the chest/face; re-label “cooling.”

3. Trace-back card
   Recall a recent irritation. Walk backward: jarāmaraṇa → jāti → bhava → upādāna → taṇhā → vedanā → phassa. Circle where you could have paused. Rehearse that pause once.

D. Cross-links

• Ch02 The Wheel & Four Periods (how the same 12 links sit in time layers).

• Ch03 Three Rounds (why kilesa/kamma/vipāka matter for practice).

• Ch08 Practice Primer: Present flow from phassa → vedanā → taṇhā.

• Ch15 Vedanā (why feeling is the lever).
