Chapter 7 · Finding the Dashas
दशानयनाधिकाराध्यायः
समरसिंहेन सर्वग्रहाणां भोग्यांशेभ्यो दशानयनमुक्तम्॥सर्वग्रहा भुक्तांशा नव संस्थाप्य भोग्यभागेभ्यः॥जातांकभुक्तवर्षे यल्लब्धं तेन संगुणयेत् ॥
Samarasimha tells how to work out the dashas (planet period) of all planets. He uses the degrees still to run. Set out all nine with their degrees gone. From the degrees still to run, find the jatanka (the number found). Divide the year by it. Multiply by what comes out.
Simple meaning: Periods from the degrees still to run: Samarasimha's method. The year is divided by the total found from these degrees.
प्रत्येकं भुक्तांशा यो यस्यास्तिराशिसंख्यांकः॥
Periods from the degrees still to run: each planet's figure, multiplied, gives its period in days.
व्याख्या॥सर्वग्रहाणां सलग्नानां भुक्तांशान् कर्मभूमौ संस्थाप्य अंशास्त्रिंशन्मध्ये शोधिताः संतो भोग्यांशास्स्युस्तेभ्यः पूर्वोक्तप्रकारेण यो जातांकस्तेन वर्षपरिमाणं भाज्यम् ॥
Degrees still to run: take each degrees-gone figure from 30. Then use the same method as before.
अयमर्थः ॥ पूर्वं ग्रहभागा हीनांशक्रमेण स्थापिताः ॥ इदानीन्ते भागास्त्रिंशन्मध्ये शोधितास्संतो भोग्यभागा वैपरीत्येन हीनांशा जातास्ते पुनर्वैपरीत्यक्रमेण पात्यांशाः कर्तव्यास्तेषां योगेन वर्षम्भजेत् ॥
Degrees still to run: the order is reversed. The remainders are made in reverse and the year is divided by their total.
