Chapter 7 · Finding the Dashas
दशानयनाधिकाराध्यायः
षडंशतुल्यास्त्वेतासां नाडिकाद्युफले दशाः ॥भवेयुर्दिवसारंभवर्तमानभहद्दतः ॥
A sixth of these are the periods in ghatikas (24-minute units) for the day's result. They start from the hadda (a planet's own small part of a sign) running in the sign at the day's start.
Simple meaning: 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.
नैसर्गिकदशा घस्रा विधुवीर्याच्च ये स्मृताः ॥
Natural periods: the first period is split into passed and coming parts by the Moon's sign.
चंद्रराशीशभुक्तैष्यभागैर्निघ्ना च तद्दशा ॥
Natural periods: the Moon's sign lord's period is split by its degrees. The part to come starts the year; the part passed ends it.
