ग्रहराशिस्वरूपवर्षप्रवेशाद्यानयनाधिकारः
श्रीमन्नीलकंठदैवज्ञैस्तु स्वल्पांतरत्वान्नोक्तमतो न कोपि दोषः ॥
The revered astrologer Nilakantha did not tell this, as the difference is very small. So there is no fault at all.
Simple meaning: Nilakantha left this out: the difference is tiny, so it is no fault.
अथ वर्षप्रवेशे तिथ्यानयनमुक्तं पद्धतिभूषणे ॥
Tithi at the year entry: years gone times 11, plus a small part, plus the birth tithi, remainder by 30. It may be one off.
नक्षत्रयोगानयनमुक्तं ताजिकसारे ॥
Nakshatra and yoga at the year entry: years gone times 10, less a 240th part, plus the birth nakshatra or yoga, remainder by 27.
लग्नानयनमुक्तं पद्धतौ ॥
Lagna at the year entry, roughly: years gone times 3.1, plus the birth lagna, remainder by 12.
