Chapter 4 · The Sahamas
सहमाध्यायः
सूर्यभुक्तानंशकांश्च पिण्डयेत्प्राग्वदाचरेत् ॥शुद्धिः कार्या धनाद्यत्र विश्रान्तिः पितृसद्म तदिति ॥
... the Sun's travelled degrees. Join them and act as before. Take away from the 2nd house on. Where the count rests, that is the sahama (special point for one life topic) of the father.
Simple meaning: 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.
ग्रहज्ञाभरणेप्युक्तम् ॥
Grahajnabharana: by day join the Sun's degrees left and the Moon's degrees gone, plus the signs between. Then check where the lagna is.
