दशानयनाधिकाराध्यायः
लग्नं चाग्रखगात्त्यजेत्तदनु तच्छ्रेयो विलग्नादधः स्थाप्यस्तद्विहगन्तदग्रखगतः शेषस्तुपूर्वादधः ॥एवं सर्वखगान्विशोध्य च ततः संस्थापयेत्पूर्ववल्लग्नात्सर्वखगाधिकं तु विवरं सर्वाधिकाधो लिखेत् ॥
Take the lagna (rising sign) from the planet ahead of it. Then set the rest below the lagna. Take that planet from the planet ahead of it. Set the rest below the earlier one. Subtract all the planets this way and set them out as before. Then take the gap from the lagna, beyond all the planets. Write it below the last, furthest planet.
Simple meaning: Yadava's method: subtract each from the next, starting at the lagna. The gap from the last planet back to the lagna goes below the last one.
चं ल सू बु शु बृ श मं ग्रहाः
Worked table: each planet's place from Aries, its remainder, and its period in days.
ल सू बु शु बृ श मं चं ग्रहाः
Yadava's worked table: each planet's place counted from the lagna, its remainder and its period in days.
शुद्धांशयोगेन भजेच्च वर्षं लब्धेन लग्नादिखगाधरस्थात्॥
Yadava's period lengths: divide the year by the total of the remainders, then multiply each remainder by it.
