सहमाध्यायः
विश्राम्यति हि तत्रर्क्षे स्यात्पुण्यसहमं विधोः ॥भोग्यादारविभुक्तन्तु निश्यन्यो विधिरादिम इति ॥
... in the sign where the count rests, there is the Punya (merit) sahama (special point for one life topic). By night, the count runs from the Moon's degrees still to travel up to the Sun's travelled degrees. The other rule is the first one.
Simple meaning: Where the count stops is the Punya point. By night, use the Moon's degrees left and the Sun's degrees gone; the rest is the same.
वामनेनापि पितृसहमानयने स्पष्टमभिहितञ्च ॥
Vamana's way for the father's point by day: Sun's degrees left, Saturn's degrees gone and the signs between.
एकीकृत्य ततः प्राग्वत् कृत्वा लग्नविचारणम् ॥
After joining, check the lagna as before. By night, start with Saturn's degrees left.
सूर्यभुक्तानंशकांश्च पिण्डयेत्प्राग्वदाचरेत् ॥
By night add the Sun's degrees gone, then subtract from the 2nd house. Where it stops is the father's point.
