सहमाध्यायः
तद्यथा ॥ वर्षप्रवेशे भौमो राश्यादिः ३ । १० लग्नेशश्चंद्रो राश्यादिः २ ।५॥ अत्र लग्नाधीशाच्चन्द्राद्भौमपर्य्यन्तङ्गणना कर्तव्या । मिथुनपञ्चांशादुपरि कर्कंदशमांशावधि गणनया जातं राश्यादिः १ । ५ ॥ लग्नाधिपोनभौमः समन्न तु कुजेन लग्नपसमम् ॥
Here is an example. At the year's entry, Mars is at 3 signs 10 degrees. The lord of the lagna (rising sign) is the Moon, at 2 signs 5 degrees. Here, count from the lagna lord, the Moon, up to Mars. Count from 5 degrees of Gemini up to 10 degrees of Cancer. The count gives 1 sign 5 degrees. Mars less the lagna lord gives the same figure. The lagna lord less Mars does not.
Simple meaning: Samarthya point, worked example: Mars at 3 signs 10 degrees, the Moon (lagna lord) at 2 signs 5 degrees. The count from Moon to Mars is 1 sign 5 degrees, which is Mars minus the Moon.
अत एव मुक्तावल्यां स्पष्टमभिहितम् ॥
Samarthya point in the Muktavali: by day, take the lagna lord from Mars. The rest of the line is unclear.
समरसिंहवाक्ये यस्माद्गणना तस्य शोध्यत्वं यदवधिगणना तस्य शोधकत्वं सर्वत्र ज्ञेयमित्यलम् ॥
General rule: the planet counted from is taken away, and the planet counted up to is the one it is taken from.
दिने गुरोश्चंद्रमपास्य नक्तं रविक्रमादर्कविधू च देवौ ॥
Same verse as Tajika Nilakanthi 3.10; see its meaning there.
