Samarasiṃha names as his source the work of Khindika,¹²³ a name derived from the Arabic al-Hindī. There is a commentary, the Daivajñasantoṣiṇī or Karmaprakāśikāvṛtti, composed by Nārāyaṇa Sāmudrika¹²⁴ in about 1725. - [Previous: c7.s1.3](https://indike.org/pramana/ins.science.pingree-1981.c7.s1.3) - [Next: c7.s1.5](https://indike.org/pramana/ins.science.pingree-1981.c7.s1.5) - [Up: c7.s1](https://indike.org/pramana/ins.science.pingree-1981.c7.s1) --- Source: [https://indike.org/pramana/ins.science.pingree-1981.c7.s1.4](https://indike.org/pramana/ins.science.pingree-1981.c7.s1.4) · Pramāṇa
