There are commentaries composed by Rāmacandra himself together with his brother, Bharata⁸⁵ (Saralā), by Dāmodara⁸⁶ (Saṅketamañjarī), and by Dīkṣita Sāṃvatsara.⁸⁷ Other works on svaraśāstra include the Yuddhajayotsava of Gaṅgārāma⁸⁸ and the Pavanavijaya or Svarodaya attributed to Śiva. Other cakras are used in interpreting nativities by Prajāpatidāsa,⁸⁹ who wrote his Pañcasvarānirṇaya or Granthasaṅgraha⁹⁰ before 1625 (the earliest manuscript was copied in 1631). There are commentaries by Prajāpatidāsa himself as well as by Appaya Dīkṣita⁹¹ and Gauḍa Bhaṭṭācārya.⁹² To Mahādeva⁹³ is ascribed a Pañcapakṣiśakuna⁹⁴ employing the five European vowels for divination; the oldest dated manuscript containing this work was copied in 1750. A related text is the Tattvārthacintāmaṇi⁹⁵ composed together with a vṛtti by Bālakṛṣṇa Vedavṛkṣa⁹⁶ at Kāśī in the 1820's. - [Previous: c6.105](https://indike.org/pramana/ins.science.pingree-1981.c6.105) - [Next: c6.107](https://indike.org/pramana/ins.science.pingree-1981.c6.107) - [Up: c6](https://indike.org/pramana/ins.science.pingree-1981.c6) ## Linked texts (2) - [Narapatijayacaryā](https://indike.org/pramana/in.astro.yatra.narapatijayacarya) — Narapati, Sanskrit - [Pavanavijaya](https://indike.org/pramana/in.astro.samhita.svarodaya.pavanavijaya) — Jīva, Sanskrit --- Source: [https://indike.org/pramana/ins.science.pingree-1981.c6.106](https://indike.org/pramana/ins.science.pingree-1981.c6.106) · Pramāṇa
