सत्योक्ते ग्रहमिष्टं लिप्तीकृत्वा शतद्वयेनाप्तम् ॥ मंडलभागविशुद्धेऽब्दा: स्यु: शेषात्तु मासाद्या: ॥ ७-१० ॥
According to the rule advocated by Satyacharya, the longitude of a planet (signs minutes etc) should be converted into minutes and divided by 200. The quotient if more than 12 should be divided by twelve and the remainder gives the longevity in years months etc for the planet concerned.
