III.27 III. PAULIŚA-SIDDHĀNTA 67 Tridinaspṛg-yoga 27. When a tithi extends throughout a day, coinciding with a part of the previous day and the next day, the occurrence is called Tridinaspṛg, (literally 'touch of three days'). (If, besides a whole tithi, parts of the previous and next tithis fall on the same day, the occurrence is called avama, literally, 'uncounted tithi'). The only thing we have done to the reading in the first half of the verse is to change śā into ṣā, which is quite warranted. But TS have changed de into di and introduced a new word, anya. Still their reading of the text cannot yield the meaning. To agree with tithitraya-sparśañat, we corrected ahnaḥ into avamaḥ, because avama alone results by contact with three tithis. The word ahnaḥ is neces- sary also, but can be understood from the context, though not mentioned, but not so, avamaḥ. If this part is left uncorrected as TS have left, the expression would be non-sensical like Sudhākara's meaning: "Because the day touches three tithis, it is called 'Three-day touching'. But Thibaut has grasped the idea here, though calling it "the conjunction touching three Tithis". NP too, have caught the idea, but since the relevant emendation to avama did not strike them, they merely say '(there is a yoga)'." [राहुः] अष्टगुणे दिनराशौ 'रूपेन्द्रियशीतरश्मि'भिर्भक्ते । लब्धा राहोरंशा भगणसमाश्च क्षिपेल्लिप्ताः ॥ २८ ॥ वृश्चिकभागा राहोः षड्विंशतिरेकलिप्तिकालुप्ताः । आदितरः प्रोह्य मुखं षड्राशियुतं तु पुच्छाख्यम् ॥ २९ ॥ Rāhu (Node) 28. Multiply the days from Epoch by 8 and divide by 151. Rāhu's motion is got in degrees etc. Add minutes equal to revolutions. (The motion becomes exact.) 29. Deduct the motion from 7ʳ 25° 59ʹ. The remainder is Rāhu's Head (what is called Dragon's Head, a popular name for the Ascending Node). Add 6 rāśis to Rāhu's Head, (Dragon's Tail or Descending Node), is got. Example 13. (a) Days from Epoch, 75,500; find Rāhu's Head and Tail. (b) Find the Head of Rāhu at Epoch, i.e. for Zero day. 27b.
