ग्रह-युद्धम् Graha Yuddha

Scan epoch 2026-09-16T12:30:00.063Z. Longitudes: Sūrya-Siddhānta II.34–43 (manda + śīghra). Latitude and geocentric distance: Nīlakaṇṭha geo-heliocentric kernel — apparent diameter and the kranti tie-break are computed, not assumed.

No active graha-yuddha among the five war-eligible grahas at the scan epoch. The nearest pair separations are visible in the table above; war requires ≤1°.

1. 3.1

   Eligible grahas: Maṅgala · Budha · Guru · Śukra · Śani. Sun, Moon, and the nodes are excluded (Sūrya Siddhānta 7.18).

2. 3.2

   Threshold: ecliptic-longitude separation ≤ 1° declares war.

3. 3.3

   Winner rule (Bṛhat Saṃhitā Ch. 17): the graha with the larger apparent diameter wins.

4. 3.4

   Tie-break: diameter difference < 0.5″ → the graha with the higher ecliptic latitude wins (kranti-victor).

5. 3.5

   Effect (classical attribution, Tier-W): BPHS 7.50 describes the loser's significations as weakened. This page flags the structural state and the winner-by-rule — it makes no life-outcome prediction.

Graha-yuddha is a geometric state of the sky, datable and checkable. We publish the rule and the data — structure, not prediction.
