Narada Purana (Jyotisha Selections) · by Vyasa
Chapter 1 · Basics and Panchanga
ज्योतिषमूलं पञ्चाङ्गं च
न्यूना चेत्स्यात्तदा भावी वामं युग्मपदस्य च ।यदान्यत्वं विधोः क्रांतिः क्षेपाचेद्यदि शुद्ध्यति ॥ १७८ ॥
In the full Narada Purana (Purva Bhaga) this is chapter 54, verse 178.
If it is less, the point is still to come. For an even quarter it goes the other way. Say the Moon's declination must be taken from its latitude. Then the quarter changes.
Simple meaning: If it is less, the point is still to come. The even quarter works the other way.
क्रांत्योर्जेत्रिज्ययाभिस्ते परमायक्रमोद्धते ।
Turn both declinations into arcs and correct the Moon by their difference.
शोध्यं चंद्राद्गते पाते तत्सूयगतिताडितम् ।
When the point has passed, take it off. Multiply by the Sun's motion and divide by the Moon's motion.
तद्वच्छशांकपातस्य फलं देयं विपर्ययात् ।
Repeat the work until the Sun's and Moon's declinations are equal.
