Chapter 4 · The Sahamas
सहमाध्यायः
लग्नस्वामिनि भौमे दिवारात्रौ च जीवाद्विशुद्धे सामर्थ्यसहमं स्यादिति ॥ अत्र सर्वत्र शोधने कृते सति यत्र योगो नोक्तस्तत्र लग्नयोगः कर्तव्यः ॥
If Mars is the lord of the lagna (rising sign), take Mars away from Jupiter. This gives the Samarthya sahama (special point for one life topic), day and night. Here, everywhere, after the taking-away, add the lagna where no adding is stated.
Simple meaning: Samarthya point when Mars lords the lagna: take Mars from Jupiter. Where no planet is named to add, add the lagna.
उक्तश्च यादवेन ॥
Adding the lagna: where no adding is named after the take-away, add the lagna.
केशवपद्धतौ सर्वत्र तनुर्योज्येति यदुक्तन्तन्मूलाभावादुपेक्ष्यम् ॥
Balabhadra sets aside Keshava's rule of always adding the lagna, since it has no source.
ताजिकसारे तु ॥
Tajikasara on the Samarthya point: by day take Mars from the lagna lord, at night the reverse.
