Chapter 7 · Finding the Dashas
दशानयनाधिकाराध्यायः
अत्र गौरीमतमहादेवमतदशा बलराममतदशा च मासप्रवेशे मासप्रवेशदिननक्षत्राज्ज्ञेया ॥ दिनप्रवेशे दिनप्रवेशस्पष्टलग्ननक्षत्राज्ज्ञेया ॥ यथा मेषे त्रयोदशांशविंशतिकलापर्यन्तमश्विनीनक्षत्रमेव ज्ञेयम् ॥ अस्या एव नामान्तरं मुद्दादशेति ॥
Here, the dasha (planet period) of Gaurimata (Gauri's view, a system of nine-planet periods), of Mahadevamata (Mahadeva's view, the same periods counted from Ardra) and of Balarama's view is found as follows. At the month entry, it is found from the nakshatra (star) of the month-entry day. At the day entry, it is found from the star of the exact lagna (rising sign). For example, in Aries, up to 13 degrees 20 minutes is Ashvini star only. Another name for this dasha is mudda (Gauri's yearly period system) dasha.
Simple meaning: Month and day periods: at the month entry use that day's star; at the day entry use the star of the lagna. These are the mudda periods.
मुद्ददशानयने सुगमोपायो मिश्रकृतः ॥
Mudda period lord of a year: years passed plus the birth star number, less 2, divided by 9; the remainder counts Sun, Moon, Mars, Rahu, Jupiter…
सू चं मं रा बृ श बु के शु ग्रहाः
Table of Gauri's periods: the nine lords with their stars, days in the year, shares in a month and shares in a day.
अत्रांतर्दशाः सुगमोपायेनसामुद्रिकग्रन्थे उक्ताः ॥
Mudda sub-periods: each planet has a multiplier, 4, 8, 5, 7, 10, 6, 9, 5, 6, from the Sun on; multiply the period by it.
