Chapter 7 · Finding the Dashas
दशानयनाधिकाराध्यायः
अथमासप्रवेशे दशानयनमुक्तं मुक्तावल्याम् ॥पात्यांशयोगेन भजेद्गतैष्यमासांतरंस्याद्गुणकोथ तेन ॥पात्यांशकास्संगुणिता दशाःस्युरुक्तक्रमान्मासफले दशानाम् ॥
Next, the Muktavali tells how to work out the dashas (planet period) at the month's entry. Take the time between the past and the coming month entry. Divide it by the total of patyamshas (degrees left after subtracting). The result is the multiplier. Multiply the patyamshas by it. These are the dashas, in the order told, for the month's results.
Simple meaning: Month periods: divide the month's length by the total of remainders, then multiply each remainder by it.
हीनांशकानुक्रमतो यथास्थलवैक्यहन्मासमिते यदाप्तम् ॥
Month periods, another way: divide the month by the total of the degrees as they stand, then multiply each by the result.
समरसिंहेन सर्वग्रहाणां भोग्यांशेभ्यो दशानयनमुक्तम्॥
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.
