But the most noteworthy and popular book on *tājika* is the Tājikanilakaṇṭhī¹³² composed by Nīlakaṇṭha¹³³ at Kāśī in 1587. This is divided into two sections, which are often presented separately; the *samjñātantra* on general *tājika*, and the *varṣatantra* on *hāyana*. There exist commentaries composed by Nīlakaṇṭha’s son Govinda,¹³⁴ who was born in 1569, at Kāśī in 1622 (Rasālā); by Viśvanātha at Kāśī in 1629; by Mādhava,¹³⁵ who was born in 1598 as the son of Nīlakaṇṭha’s son Govinda, at Kāśī in 1633 (Śiśubodhinī); and by Harṣadhara (Śrīphalavardhinī).
