Chapter 7 · Finding the Dashas
दशानयनाधिकाराध्यायः
षष्ट्याप्तान्तर्दशा तस्य जायतेतिपरिस्फुटा ॥यस्य वर्षे भवेत्तस्य प्रथमा च दशा भवेत् ॥ २ ॥
Divide by sixty. That gives that planet's antardasha (sub-period), quite clearly. The planet whose year it is has the first antardasha.
Simple meaning: Mudda sub-periods: divide by 60; the year's own planet takes the first sub-period.
अन्यास्तदग्रिमस्थानादेवमन्तर्दशा अपि ॥
Mudda sub-periods: the rest follow in order; a bad planet's year brings sorrow, a good one's brings happiness.
अथ सूर्यादीनांदशान्तर्दशाफलं ॥ तत्रैव ॥
Sun inside the Sun's mudda period: fear from the king, bile trouble, trouble for kin, spending.
शांतिं रिपुप्रतापानां नैरुज्यं धनसंपदाम् ॥
Moon inside the Sun's mudda period: enemies calm down, good health and riches.
