Chapter 4 · The Sahamas
सहमाध्यायः
ग्रहसहमानयनं समरसिंहटीकायां तुकज्योनिर्विद्भिरुक्तम् ॥ ग्रहमग्रस्थग्रहात्संशोध्य लग्नं योज्यं ग्रहसहमं भवेत् ॥
The working of the planet sahamas is told in the commentary on Samarasimha, by astrologers. Take the planet away from the planet that stands ahead of it. Add the lagna (rising sign). That is the planet's sahama (special point for one life topic). (Our text is unclear here: the word before 'astrologers'.)
Simple meaning: Planet sahama: take the planet from the planet ahead of it, then add the lagna.
एवं मुथहाराशिसंयोगान्मुथहासहमं च भवति ॥
Muntha point: made the same way as a planet sahama, by bringing in the muntha's sign.
उक्तश्च मुथहाराशिसंयोगान्मुथहासहमञ्च तत् ॥
Muntha point: made by bringing in the muntha's sign.
अथ भावसहमानयनमुक्तं रोमकेण ॥
House sahamas: by day the house less its lord, at night the lord less the house, then add the lagna.
