Chapter 7 · Finding the Dashas
दशानयनाधिकाराध्यायः
भुक्ततुल्या दिनप्रख्यावर्षान्तेन्याग्रहहद्दजा ॥लग्नहद्देशतो हद्दादशाखाग्न्यंशकावधिः ॥४॥
At the year's end comes one more period, from a planet's hadda (a planet's own small part of a sign). It equals the passed part, in days. The hadda dasha (planet period) runs from the lagna's (rising sign's) hadda lord up to the 30th degree.
Simple meaning: Hadda periods: at the year's end, the first lord returns with its passed part. The count runs through the sign to 30 degrees.
यातैष्यमासांतरवासराद्यं हन्यात्स्वरामावधिभोग्यभागैः ॥
Hadda periods in the month: the month's span times the hadda degrees, divided by 30, gives each planet's share.
अत्रोदाहरणम्॥तत्र वर्षप्रवेशे स्पष्टलग्नं राश्यादि ४।८।५३।१०॥ अत्र संज्ञातंत्रोक्तं ॥ मेषेंगतर्काष्टशरेषु भागा इत्यादिना हद्दांशाद्द्वादशगुणा भौमादिपंचग्रहाणां वर्तमानहद्देश्वरमारभ्य सौरदशादिनानि वर्षे भवंति॥
Hadda example: the lagna is Leo 8;53. Hadda degrees times 12 give each of the five planets' days, starting from the current hadda lord.
मे वृ मि क सिं क तु वृ ध म कुं मी
Table of hadda degrees: for each sign, its five hadda lords and their degrees. Each sign adds up to 30.
