Chapter 4 · The Sahamas
सहमाध्यायः
एकीकृत्य ततः प्राग्वत् कृत्वा लग्नविचारणम् ॥रात्रौ वर्षविलग्नश्चेच्छनिभोग्यांशकास्ततः ॥
... Having joined them, check the lagna (rising sign) as before. If the year lagna is taken by night, take Saturn's degrees still to travel, and then...
Simple meaning: 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.
यदुनरसिंहनन्दनेन दिवाकरेण स्वकृतवर्षपद्धतिटीकायां सैकतासंस्कारो वामनेनोक्त इत्युक्तम् ॥ तन्मतिभ्रमेण ॥
Divakara's claim that Vamana gave the add-one-sign step is wrong.
ताजिकशास्त्रावबोधरूपायान्ताजिकमुक्तावल्यामप्युक्तम् ॥
Tajikamuktavali: if the lagna is between, subtract its degrees left. If not, add its degrees gone. Count from the 2nd house for every sahama.
