What is Graha Yuddha (Planetary War)?
When two true planets (excluding Sun, Moon, Rahu, Ketu) come within 1° of each other, they enter Graha Yuddha (planetary war). The planet with higher longitude generally wins, though some traditions use brightness or latitude. The winner absorbs the loser's energy — the victor gains strength while the defeated planet's significations suffer. Mars versus Mercury is the most dramatic war (warrior vs scholar). Jupiter rarely loses due to its luminosity. Venus and Saturn wars are rare but impactful. The war affects both natural and functional significations.
