At some time after 600 was written the *pūrvakhaṇḍa* of what was to become known as the *Bṛhatpārāśarahorā*²⁷ ascribed to Parāśara.²⁸ It computes the *ayanāṃśa* or precession, due to a misunderstanding of Āryabhaṭa, from 522 (BPH *pūrva* 3, 31), and is deeply indebted to the BJ; it also has borrowed two verses from Sphujidhvaja (BPH *pūrva* 2, 47–48 equal YJ 1, 59–60). 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).
