Somewhat better known is a Saura karaṇa, the Sūryapakṣasāraṇa¹⁶⁴ or Khacarāgama composed by Viṣṇu; its epoch is 7 March 1608. A commentary, Udāharaṇa, was written on it by Viśvanātha already in 1612. The fact that the karaṇa belongs to the Saurapakṣa and that it was known to Viśvanātha within four years of its composition makes it likely that Viṣṇu lived in Benares, in which case he was probably the Viṣṇu who instructed Kṛṣṇa,¹⁶⁵ who wrote the Bijāṅkura in about 1600, and was himself the pupil of Gaṇeśa’s nephew, Nṛsiṃha.
