It deals with aṣṭakavarga (1; cf. pūrva 17–23), the six kinds of planetary strength (ṣaḍbala) (2); computing planetary strength (iṣṭakaṣṭavarṇana) (3); raśmi (4; cf. VYJ 56); the native’s passage through this world (lokayātrā) (5–9); āyurdāya (10–12; cf. pūrva 24–25); good fortune (bhāgya) (13); time units and the fruition of astrological indications (14–17); interrogations (praśna) (18); and, in conclusion, a table of contents (19) and a praise of the work (20). The uttarakhaṇḍa was commented on by Govindasvāmin in Kerala in about 850 (Prakaṭārthadīpikā), while the whole BPH was commented on by Śrīdhara and Harikṛṣṇa at Jayapura in about 1875. Despite the questionability of the authenticity of some parts of the pūrvakhaṇḍa, the BPH represents some notable developments in the long process by which the original Hellenistic astrology that was transmitted to India in the second century was made increasingly complex so as to generate predictions more closely approximating reality; these developments are particularly noticeable in the theories of āyurdāya.daśās, and the computation of planetary strength. - [Previous: c7.43](https://indike.org/pramana/ins.science.pingree-1981.c7.43) - [Next: c7.45](https://indike.org/pramana/ins.science.pingree-1981.c7.45) - [Up: c7](https://indike.org/pramana/ins.science.pingree-1981.c7) --- Source: [https://indike.org/pramana/ins.science.pingree-1981.c7.44](https://indike.org/pramana/ins.science.pingree-1981.c7.44) · Pramāṇa
