Parāśara
Purāṇic · Vasiṣṭha lineage · Jyotiṣa
Maharṣi Parāśara was the grandson of Vasiṣṭha and the father of Veda Vyāsa. The Viṣṇu Purāṇa is told by Parāśara to his disciple Maitreya, and the Parāśara Smṛti, a law-book, bears his name.
For Vedic astrology he is the most important of all sages: the Bṛhat Parāśara Horā Śāstra, the root text of Jyotiṣa as practised today, is presented as his teaching to Maitreya. It lays out the houses, signs, divisional charts, yogas and the Vimśottarī daśā system. Scholars hold that the text as we have it was compiled over centuries, but astrologers still call their system “Parāśarī”.
