Chapter 4 · The Sahamas
सहमाध्यायः
तत्पूर्वलब्धसंयुक्तं नख २० भक्तं लवादिकम् ॥तद्धनं सौम्यगोलस्थे सहमे याम्यगे ऋणम् ॥अतीव सहमं स्पष्टं जायते गणकोक्तित इति ॥
... Add that to the earlier result. Divide by 20. The answer is in degrees and so on. Add it when the sahama (special point for one life topic) is in the north half of the sky. Take it away when the sahama is in the south. The sahama then becomes very exact, by the astrologers' words.
Simple meaning: 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.
ग्रहसहमानयनं समरसिंहटीकायां तुकज्योनिर्विद्भिरुक्तम् ॥ ग्रहमग्रस्थग्रहात्संशोध्य लग्नं योज्यं ग्रहसहमं भवेत् ॥
Planet sahama: take the planet from the planet ahead of it, then add the lagna.
