Graha Yuddha

Definition

Graha Yuddha — literally a "planetary war" — is the contest two planets are said to fight when they fall into very close conjunction: within one degree of each other, or on the same degree, in the same sign or house. One is reckoned the winner, the other the loser, and the defeated planet is weakened in its results, so the bhava (house) and significations it governs lose potency. The luminaries stay out of it: the Sun burns a planet by combustion instead, and several sources also exclude the Moon and the nodes.

In Tradition

Across the classical and modern Jyotish literature, astrologers treat graha yuddha as a gauge of relative planetary strength: the planet judged the winner gains strength while the loser is weakened. In the strength-based accounts, the difference between the two planets' strengths is added to the winner and subtracted from the loser. The sources agree that the luminaries do not enter such a war, but they part ways over the exact criterion that decides who wins.

In Practice

A jyotishi (Vedic astrologer) uses graha yuddha to fine-tune the strength of two closely conjunct planets, weakening the loser along with the houses and significations it rules — a losing benefic may be unable to deliver its results, while a losing malefic can turn harmful. Which planet wins depends on the source. Many authors — including Frawley, Levacy, and Santhanam's note on BPHS — give it to the planet of lower longitude (fewer minutes); the Uttara Kalamrita and Varahamihira favour the one further north (bright, with a full orb); deFouw and Svoboda the one of higher latitude; Cole the higher degree; Kannan the strongest planet. In Parasara's strength rule, the Shadbala difference is added to the victor and deducted from the vanquished as part of Kala Bala. It also serves mundane prediction — reading wars, calamities, and the fate of the peoples a planet governs — and a planet defeated in war is held not to aspect, even when it appears to.

Historical Origin

Graha yuddha is recorded across the classical Sanskrit texts — the Brihat Parasara Hora Sastra (Ch.11 and Ch.27, trans. Santhanam), Varahamihira's Brihat Samhita (Adhyaya IX and XVII, trans. Sastri and Bhat), and Kalidasa's Uttara Kalamrita (trans. Sastri) — and modern writers have carried it forward, among them Frawley, Levacy, deFouw and Svoboda, Cole, Kannan, and Mehta and Rao.
