त्रयाणां वीर्य्यमार्गेण योगस्त्रैक्य उदाहृतः ॥अथवा सुगमोपायस्त्रैक्यार्थंविनिरूप्यते ॥ ६ ॥
The total of the three, by the way of virya, is called the traikya (the sum of three corrections). Or an easy method is set out for finding the traikya.
Simple meaning: The traikya is the total of the three corrections; an easy method follows.
सायनस्फुटसूर्य्यस्य भुक्तांशास्स्वोदयैर्हताः ॥
Easy traikya: the Sun's gone degrees times the rising time of its sign, divided by 30, plus the rising times of the signs from Aries before it.
षष्टिभक्तन्नाडिकादि अथ मध्यमभास्करः ॥
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.
