Chapter 8 · Month Chart and Monthly Results
मासप्रवेशादिविचाराध्यायः
अथ स्वाभीष्टमासस्य संख्यारूपविवर्जिता ॥तत्तुल्यमासगतिजकोष्ठस्थफलसंयुतः ॥ १४ ॥
Now, take the number of the chosen month, less one. The result standing in the cell of the month-motion table, equal to that, is added to the Sun.
Simple meaning: For the month's Sun: take the chosen month number less one and add the table result for it.
जन्मार्को मध्यमोभीष्टमासपार्श्वे भवेद्रविः ॥
The mean Sun near the chosen month is found from the birth Sun. The month number less one, times 30, is added.
स्वजन्माहर्गणेभीष्टार्कसंबंधी भवेद्गणः ॥
For the chosen month, work out the true Sun as told, with its motion and the traikya.
ततस्स्वाभीष्टसूर्य्यस्य मासार्केनांतरं चरेत् ॥
Take the gap between the chosen Sun and the month Sun and divide it by the true motion. That gives days.
