Moreover, it was used by Kalyāṇavarman, who wrote in ca. 800 (BPH \*pūrva\* 2, 49–52 = S 5, 21–24; and BPH \*pūrva\* 21, 17–48 equal S 21, 21–52; cf. S 21, 6), and its existence is presupposed by the author of the \*uttarakhaṇḍa\*, which was commented on by Govindasvāmin in ca. 850. Therefore, the \*pūrvakhaṇḍa\* must have been written between ca. 600 and 750, and the \*uttarakhaṇḍa\* after the \*pūrvakhaṇḍa\* but before ca. 800. The \*pūrvakhaṇḍa\* in fifty-one \*adhyāyas\* is a rich but confused collection of material, much of which is unprecedented: the basic elements of astrology (2–3); aspects (4); the nature of the neonate native (5–7); the planetary operators (kāraka) (8–9); the astrological places (10); the mounted places (ārūḍha) and their next places (upapada) (11–12); the killer (māraka) planets (13); the astrological places and their lords (14–15); curses in previous incarnations (pūrvajanmaśāpa) (16); aṣṭakavarga (15–20); nābhasa and other yogas (21–22); smashing the killer planet (mārakabheda) (23); āyurdāya (24–25); death (26–27); rājayogas and yogas leading to wealth and poverty (28–31); rebirths (32); pleasure and sorrow (33); various conditions (avasthās) of the planets (34); the varieties of daśās, including vimśottarī, ṣoḍaśottarī, dvādaśottarī, aṣṭottarī, pañcottarī, śatābdikā, caturaśītyabdikā, dvi-saptatikā, ṣaṣṭihāyanī, and ṣaṭtriṃśatkā (35);²⁹ vimśottarīdaśās (36); antardaśās and their subdivisions: upadaśās, sūkṣmadaśās, and prāṇadaśās (37–48); kālacakradaśās (49); caradaśās (50); and the sudarśanacakra (51). - [Previous: c7.38](https://indike.org/pramana/ins.science.pingree-1981.c7.38) - [Next: c7.40](https://indike.org/pramana/ins.science.pingree-1981.c7.40) - [Up: c7](https://indike.org/pramana/ins.science.pingree-1981.c7) ## Linked texts (3) - [Bṛhatparāśarahorāśāstra](https://indike.org/pramana/in.astro.hora.yavana.brhatparasara.3.31) — Parāśara, Sanskrit - [Sārāvalī](https://indike.org/pramana/in.astro.hora.yavana.saravali.21.6) — Kalyāṇavarman, Sanskrit - [Vṛddhayavanajātaka](https://indike.org/pramana/in.astro.hora.yavana.vrddhayavanajataka) — Mīnarāja, Sanskrit --- Source: [https://indike.org/pramana/ins.science.pingree-1981.c7.39](https://indike.org/pramana/ins.science.pingree-1981.c7.39) · Pramāṇa
