CH28: Sources & Sutta Sigla • Diagram Legend • Index

At-a-glance: Reference • How to read this book’s maps • Find-it-fast

A. Sources & citation practice (primary only)

• Canon anchors used throughout (sigla → what we cite them for):

  • SN 12.1 — Paṭicca-samuppāda: forward & cessation chain; placement of 11–12 dukkha items.

  • SN 12.2 — Vibhaṅga: per-link definitions/enumerations (six feelings, six cravings, four clingings, three becomings, etc.).

  • SN 36 — Vedanā-saṁyutta: three tones (pleasant/painful/neither) and working with feeling.

  • SN 35 — Saḷāyatana-saṁyutta: six bases and contact dynamics.

  • SN 22 — Khandha-saṁyutta: five aggregates; “processes, not a self.”

  • SN 5.10 — Vajirā: “With parts assembled we say ‘being’…”.

• How we cite: short form in the text (e.g., “SN 12.2”) and chapter Sources strips list only sigla. Full bibliographic details belong in your course syllabus or slide speaker notes.

• Scope promise: this handbook keeps definitions/enumerations to SN 12.1–12.2; other suttas support practice framing, not to alter the 12-link map.

B. Diagram legend (how to read the figures)

• Twelve links (fixed order):
  avijjā → saṅkhārā → viññāṇa → nāma-rūpa → saḷāyatana → phassa → vedanā → taṇhā → upādāna → (kamma)bhava → jāti → jarāmaraṇa.
  Arrows = conditionality; dashed arrows denote cessation reading.

• Four periods (outer frames):
  Past Cause | Present Effect | Present Cause | Future Effect.
  (The chain is one line; the frames are placements for teaching.)

• Three rounds (color/pattern overlay):
  Kilesa = avijjā, taṇhā, upādāna • Kamma = saṅkhārā, (kamma)bhava • Vipāka = the rest.
  Accessibility note: Do not rely on color alone—each round also has a distinct pattern/shape key (e.g., diagonal hatch for Kilesa, dot grid for Kamma, plain for Vipāka).

• Three connections (beacons):
  C1 saṅkhārā → viññāṇa (Past→Present, Kamma→Vipāka) • C2 vedanā → taṇhā (Present pivot, Vipāka→Kilesa) • C3 (kamma)bhava → jāti (Present→Future, Kamma→Vipāka). Beacons are drawn as labeled tabs above their arrows.

• Present-flow highlight: phassa → vedanā → taṇhā is boxed or haloed to signal the practice hinge (Ch08, Ch15–16).

• Khandha present-aspect inset: a five-icon strip (rūpa • vedanā • saññā • saṅkhāra • viññāṇa) sits beside each door demo (Ch21–22).

• Typography: Pāli with diacritics; no Burmese script in body text. All labels appear outside arrows (avoid clutter).

• Print & accessibility: minimum 9-pt labels; 4.5:1 contrast; each diagram has a one-sentence alt text beneath the figure.

• QR layout (for every page footer): keep a 4× module quiet zone around each code; size ≥ 20–30 mm square for A4/Letter; default ECC M (use H on textured backgrounds); in the PDF, each QR is clickable and has functional alt text (e.g., “QR to audio: Guided vedanā practice”).
