Chandra Shuddhi — Combined Moon Purity (Tara + Chandra Bala)
One of the Pancha Shuddhi — assesses the Moon's purity from both nakshatra and sign positions simultaneously.
Calculating Chandra Shuddhi...
What is Chandra Shuddhi?
Tara Bala (Nakshatra Level)
Counts transit Moon's nakshatra from birth nakshatra in cycles of 9 — each cycle yields a Tara type (Janma, Sampat, Vipat…). Works at 13°20' resolution.
Sampat, Kshema, Sadhaka, Mitra, Ati-Mitra — auspicious
Janma — moderate
Vipat, Pratyak, Vadha — inauspicious
Chandra Bala (Sign Level)
Counts transit Moon's sign from birth Moon sign. Works at 30° resolution — coarser than Tara Bala.
Positions 3, 6, 7, 10, 11 — favorable
Positions 1, 2, 5, 9 — neutral
Positions 4, 8 (Ashtama), 12 — unfavorable
Merge rule: Tara Bala (finer granularity) takes precedence. Hard malefic Taras (Vadha, Pratyak) override any favorable Chandra Bala. When both align, the verdict is decisive — when they disagree, Tara Bala governs the severity.
