Chapter 7 · Finding the Dashas
दशानयनाधिकाराध्यायः
अथ मासदशासौरसावनीकरणेप्रकारांतरं तत्रैवोक्तम्॥वर्षा ३६५ र्कभागेन ३०।२६।२७ यदोनसादनादशाइमाः स्युर्द्युसदां दिनादिकाः॥तदेष्टमासांतरवासरैः कियन्मिताः प्रसाध्या इति वात्र मासजाः ॥
Next, another way, stated in the same text, to make the month periods solar-civil. A twelfth of the year (365) is 30;26;27. By it, the planets' periods are so many days. How many are they by the days between the chosen month entries? So find the month periods here. (Our text is unclear here: the words right after the figure do not read cleanly.)
Simple meaning: Month periods to solar-civil days: a rule of three with the days between the month entries.
अथ वर्षे ग्रहाणां निसर्गदशा तत्रैवोक्ता ॥
Natural periods: Moon 3, Mars 6, Mercury 27, Venus 60, Jupiter 54, Sun 60, Saturn 150 days. They start from the Moon's sign lord.
षडंशतुल्यास्त्वेतासां नाडिकाद्युफले दशाः ॥
Natural periods in the day: a sixth of each year figure, in ghatikas, starting from the current hadda lord.
वर्षे चंद्रस्य सबलत्वे चंद्रराशीशक्रमतो निसर्गदशेश्वराः स्युः वर्षदशाया द्वादशांशेन मासदशा ज्ञेया ॥ वर्षदशा षडंशेन घटिकाद्या दिनदशा भवति ॥
Natural periods: start from the Moon's sign lord. Month periods are a twelfth, day periods a sixth, of the year figures.
