Chapter 4 · The Sahamas
सहमाध्यायः
विभजेदंशकैर्लब्धं पृथगेव निधापयेत् ॥तथैव निजदेशोत्थमुदयं प्राप्तकञ्च यत् ॥
... Divide it by the degrees. Keep the result apart. In the same way, take the rising time of one's own place, and what is found from it...
Simple meaning: Correcting the sahama, steps two and three: divide, keep the result, then do the same with the local rising time.
तत्पूर्वलब्धसंयुक्तं नख २० भक्तं लवादिकम् ॥
Correcting the sahama, last step: add the two results, divide by 20. Add it in the north, take away in the south.
सहमे स्पष्टीकरणमुक्तं रोमकेण ॥
Romaka's second rule: add the two rising-time figures, divide by ten. Add in the north, take away in the south.
अनयोः प्रयोजनं जीर्णताजिके ॥
Why correct the sahama: when its lord looks at it exactly, it has strength and the sahama is gained.
