Chapter 8 · Month Chart and Monthly Results
मासप्रवेशादिविचाराध्यायः
षष्टिभक्तन्नाडिकादि अथ मध्यमभास्करः ॥सायनोस्यांशषड्भागो नाडिकादि फलम्भवेत् ॥८॥
Divided by sixty, it is in ghatikas (24-minute unit) and so on. Now the mean Sun: take the sayana (tropical) mean Sun. The sixth part of its degrees gives the result in ghatikas and so on.
Simple meaning: Easy traikya: divide by 60 for ghatikas. For the mean Sun, the sixth part of its tropical degrees gives ghatikas.
उभयोरन्तरन्त्रैक्यसंज्ञकं स्यात्कलादिकम् ॥
The gap between the two is the traikya. The sentence goes on in the next verse.
हीनस्त्रैक्यमृणं सूर्य्ये विज्ञेयं धनमन्यथा ॥
If the Sun's gone ghatikas are less, the traikya is taken away; otherwise it is added. The mean Sun is corrected by it.
अस्य प्रस्फुटता प्राग्वत्सूक्ष्मोर्कस्स्यात्परिस्फुटः ॥
The true Sun is made as before. The birth Sun is made true the same way.
