Chapter 7 · Finding the Dashas
दशानयनाधिकाराध्यायः
उदाहरणम् ॥ पात्यराशिग्रहाणां योगो राश्यादिः १०।०।०।० अनेनांशीकृतेन ३००सौरवर्षमिति ३६० भक्तालब्धं दिनादि ध्रुवकः १।१२ अनेन शोधिता ग्रहा अंशीकृता गुणिता जाताः सर्वेषान्दशादिवसाः ॥ यादवेनतु राश्यादिग्रहाणान्दशाप्रकारान्तरेणोक्ता
An example. The total of the planets' remainders, in signs, is 10 signs 0 degrees 0 minutes 0 seconds. In degrees it is 300. Divide the solar year, 360, by it. The dhruvanka (fixed multiplier) is 1 day 12 ghatikas (24-minute unit). Multiply the subtracted planets, made into degrees, by it. These are the dasha (planet period) days of all. But Yadava gives the dashas of the planets by signs in another way:
Simple meaning: Worked example: the remainders total 300 degrees. 360 divided by 300 gives 1 day 12 ghatikas.
लग्नादिरिःफान्तगतग्रहेषु योल्पो भपूर्वो हि खगस्स चादौ ॥
Yadava's order: list the planets from the lagna onward, by how far they stand from it.
लग्नं चाग्रखगात्त्यजेत्तदनु तच्छ्रेयो विलग्नादधः स्थाप्यस्तद्विहगन्तदग्रखगतः शेषस्तुपूर्वादधः ॥
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.
