Contemporary by Durlabharāja and Jagaddeva was Narapati,⁷¹ who completed his Narapatijayacaryā or Svarodaya⁷² at Aṇahilanagara in Saurāṣṭra in 1177. This work describes various arrangements (cakras) of letters associated with time divisions and astrological entities, magical pictures of animals and objects (also called cakras), and arrangements of nakṣatras, months, and numbers relative to the directions (bhūmis), all of which promote the military victory of their user. Narapati names as his sources (1, 4–10) seven yāmalas (of Brahma, Viṣṇu, Rudra, Ādi, Skanda, Kūrma, and Devī), the Yuddhajayārṇava, the Svarabhairava, the Raṇahvayatantra, the Jayapaddhati, and various other tantric texts. The NJ was commented on by Narahari⁷³ during the reign of Bhairavendra, who ruled Mithilā from ca. 1480 till ca. 1515 (Vyākhyāplava), and by Harivamśa Pāṭhaka in ca. 1500 (Jayalakṣmī); the latter was revised by Harivamśa’s son, Mahādeva,⁷⁴ in 1520. Based on the NJ is the Balatantramahārṇava of Ādityadeva,⁷⁵ on which a ṭīkā in Telugu was written by Daivajñadāsa,⁷⁶ and the Sāroddhāra composed by Śraddhā Ṛṣi in about 1837.
