Jyotihshastra: Astral and Mathematical Literature c8.s1.3

c8.s1.3

The earliest separate treatises on yātrā that we have are the three composed by Varāhamihira in the sixth century: the Ṭikanikayātrā,⁵² the Yogayātrā,⁵³ and the Bṛhadyātrā.⁵⁴ Verses from each of these works occur in the other two. In addition to the omens and astrology proper, the BY (18), following the lead of Sphujidhvaja (YJ 76, 66 and 77, 1), gives detailed instructions for the worship of the planets (grahayajña). Commentaries on the YY and the BY were composed by Bhaṭṭotpala in Kāśmīra in about 970, and on the BY by Sūryadeva at Gaṅgāpura in the early thirteenth century; of the two commentaries on the BY all that now survives seems to be a miserable fragment of Bhaṭṭotpala’s. Varāhamihira refers to Bādarāyaṇa⁵⁵ as one of his authorities, and Bhaṭṭotpala in his ṭīkā on the YY cites many verses from a Bādarāyaṇīyayātrā, of which a few manuscript copies are known.⁵⁶
