Chapter 7 · Finding the Dashas
दशानयनाधिकाराध्यायः
अथ नैसर्गिकादिदशादिवसानां मासे दिने च स्पष्टीकरणमुक्तं तत्रैव ॥नैसर्गिका ये दिवसा निरुक्ता गौरीमतान्मासफलार्थमत्र ॥गतैष्यमासांतरसङ्गुणास्ते खाग्न्युद्धृतास्स्पष्टतरा भवेयुः ॥ १ ॥निरुक्तवच्चाद्य दशागतैष्यमाद्यं तयोः स्यादपि तत्र मासे ॥
Next, the same text tells how to make the natural and other period days exact. This is for the month and the day. The natural days stated here are for the month's result, by Gaurimata (Gauri's view, a system of nine-planet periods). Multiply them by the gap between the passed and coming month entries. Divide by thirty. They become more exact. As stated, the passed and coming parts of the first period also apply there, in the month.
Simple meaning: Natural periods in the month: by Gauri's view, the days times the month's span, divided by 30, become exact.
बल्लभद्रमतोक्तानां गौरीवत्स्पष्टता मता ॥
Balabhadra's periods: they are made exact the same way as Gauri's.
नैसर्गिकदशाहानां तद्वदेव स्फुटीकृतः ॥
Natural periods in the month: made exact the same way, with the first period split as before.
गतैष्यदिनविश्लेषनाडिकाद्यनुसारतः ॥
Periods in the day: use the gap between two day entries to find each period in ghatikas.
