Chapter 4 · The Sahamas
सहमाध्यायः
अथ सहमस्पष्टीकरणं रोमकताजिके ॥लंकोदयस्य भुक्तांशाः स्वोदयस्य तथाहृताः॥सहमांशैर्द्वयोरैक्यन्दशभक्तन्दलीकृतम्॥सौम्यगोले धनम्प्रोक्तं याम्यगोले तदन्यथेति ॥
Next, the correcting of the sahama (special point for one life topic) is told in the Romaka Tajika. Take the degrees passed with the Lanka rising time. Do the same with the place's own rising time. Work them with the sahama's degrees. Add the two. Divide by ten. Then halve it. When the sahama is in the north half of the sky, add this. In the south half, do the other.
Simple meaning: Correcting the sahama: work its degrees with the Lanka rising time and the local rising time, add, divide by ten, halve. Add in the north, take away in the south.
एतत्स्पष्टमुक्तं विश्वनाथताजिके ॥
Correcting the sahama, step one: in the sahama's sign, take the Lanka rising time.
विभजेदंशकैर्लब्धं पृथगेव निधापयेत् ॥
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.
