c8.16

Two of the Jaina scholars in the circle of Vastupāla, the minister of the Vāghelas Lavaṇaprasāda and Vīradhavala in Gujarāt from 1220 till 1240, wrote popular works on muhūrta. Udayaprabha Sūri¹⁰ composed an Ārambhasiddhi or Pañcavimarśa¹¹ in 412 verses, on which Hemahaṃsa wrote a vārttika at Āśāpallī (Ahmadābād, Gujarāt?) in 1457 (Sudhīśṛṅgāra). And Naracandra Sūri¹² was the author of a Jyotiṣasāra or Nāracandra¹³ in 4 prakaraṇas, on which a ṭippaṇaka was composed by Sāgaracandra Sūri before 1468, when the earliest dated manuscript was copied. Neither author, of course, deals with the proper moments for performing saṃskāras.
