Chapter 7 · Finding the Dashas
दशानयनाधिकाराध्यायः
अथगौरीमतानयनं महादेवमतेन च ॥गौरीमतदशा जन्मर्क्षमासदिनानि दिने षडंशा दशा ज्ञेया वर्षे द्वादशांशो मासः ॥ महादेवमते आर्द्रातः ॥३॥वर्षे दशादिनानि सौराणि दिनप्रवेशे दशा घटीरूपा ते च ॥
Next, finding the periods by Gaurimata (Gauri's view, a system of nine-planet periods) and by Mahadevamata (Mahadeva's view, the same periods counted from Ardra). Gauri's dasha (planet period) goes from the birth nakshatra (star). For the month and the day: in a day, a dasha is a sixth part. A month's dasha is a twelfth part of the year's. In Mahadeva's view, count from Ardra. In the year, the dasha days are solar days. At the day entry, the dashas are in ghatika (24-minute unit).
Simple meaning: Gauri's and Mahadeva's periods: Gauri counts from the birth star, Mahadeva from Ardra; month periods are a twelfth, day periods a sixth.
दशानयनमुक्तं मुक्तावल्याम्॥
Gauri's periods: counted from the birth star, with nine lords from the Sun to Venus.
दशेशा वह्निभा ज्ञेयाः क्रमात्रिः परिवर्तनात्॥
Gauri's period lords: counted from Krittika, three rounds of nine stars; days begin 18, 30, 21.
वेदेषवो ५४ नागकृता ४८ मुन्यर्थाः ५७ क्षितिसायकाः५१॥
Gauri's period days, continued: 54, 48, 57, 51, 21, 60; for a month, take a twelfth.
