📖 Lesson → 📝 Workbook → 📊 Application → ✅ Quiz

Superseded by the Chapter 5 Workbook in the v2 redesign (see COURSE_V2_MIGRATION_REPORT.md). Kept here for provenance only — this file is no longer part of the live student path.

(Short-to-moderate — matching this lesson's reference-only, single-chapter scope; more items than the narrowest single-technique quizzes since five distinct sub-procedures are covered.)

Recall

  1. Name the five outputs of Chapter 5's method, in order.
  2. What are the Ghati/Pala/Vipala conversion ratios?

Understanding

  1. Explain why the Moon required its own separate Bhayaata/Bhabhoga method rather than the same Chaalana correction used for the Pankti-table planets.
  2. Explain the difference between Swodaya and Lankodaya, and why each is used for a different calculation (Ascendant vs. 10th House).

Application

  1. Convert 2 hours 20 minutes of clock time into Ghati-Pala (using BPHS's stated ×2½ shortcut).
  2. An arc from the Ascendant (2s15°) to the 4th House (5s15°) is trisected. What is one Kshepaka's value, and what is the resulting 2nd House?

Source Awareness

  1. Is the Hapur worked example (2-6-1951) part of Parashara's own verse text, or translator commentary? How do you know?

Target: ~80% correct before treating the lesson as mastered.

Check Answers
  1. Time-corrected Pankti position → Moon's exact position → Ascendant → 10th House → remaining ten houses.
  2. 1 day = 60 Ghati; 1 Ghati = 60 Pala; 1 Pala = 60 Vipala.
  3. The Moon's motion is fast and uneven enough that the ordinary Chaalana correction (fine for the other, slower Pankti-listed planets) wasn't precise enough — a dedicated Nakshatra-based method (Bhayaata/Bhabhoga) was used instead.
  4. Swodaya = local-latitude sign-rising-time (used for the Ascendant, a horizon-dependent point); Lankodaya = equatorial sign-rising-time (used for the 10th House, a meridian-dependent point) — different reference frames for different kinds of astronomical points.
  5. 2h20m × 2½ → 5 Ghati – 50 Pala.
  6. Arc = 5s15° − 2s15° = 3s0° = 90°. One Kshepaka = 1s0° (30°). 2nd House = 2s15° + 1s0° = 3s15°00′00″.
  7. Translator commentary. The Hapur example (dated 2-6-1951, well after Parashara's era) appears in the prose Notes following the verses, not within the numbered shloka text itself.
