Chapter 7 · Finding the Dashas
दशानयनाधिकाराध्यायः
स्वामिमित्रशुभैर्दृष्टे लग्ने मध्यफलं भवेत् ॥इति लग्नदशाफलम् ॥
If its lord, its friends or good planets give drishti (a planet's look) to the lagna (rising sign), the result is middling. This ends the results of the lagna's dasha (planet period).
Simple meaning: Lagna's period: if its lord, friends or good planets look at the lagna, the result is middling.
अथ ग्रहाणां वर्षेशफलवद्दशाफलमित्युक्तं तेजास्सिंहेन ॥
Planet periods: a planet gives in its period what it gives as year lord, good, middling or low by its strength.
अथान्तर्दशानयनं वर्षतन्त्रे ॥
Finding sub-periods: treat the period like a year and divide it the same way; the period lord's own sub-period comes first.
अयमर्थः ॥ पूर्वं हीनांशवशेन पात्यांशाश्चनिष्पादितास्तत्र पात्यांशयोगेन वर्षस्थानाभिषिक्तं दशामानं भजेल्लब्धमन्तर्द्दशानयने ध्रुवको दिनादिकस्तेन ग्रहपात्यांशाः पूर्ववद्गोमूत्रिकया गुणिताः षष्ट्योपर्युपरियुता ग्रहस्यान्तर्द्दशामानं दिनादिकं भवेत् ॥
Finding a sub-period: divide the period by the total of the leftover degrees; multiply each planet's leftover degrees by that figure.
