History of Vedic Astrology
The first Indian astronomical text to define the weekday was the Āryabhaṭīya (born AD 476). He wrote lot of scriptures in 5’Th century and generally called a Mathematician, The text was written in Sanskrit (ancient Indian language) and divided into four sections, covering a total of 121 verses that describe different results using a mnemonic style typical for such works in India.
- Gitikapada: (13 verses): large units of time—kalpa, manvantra, and Yuga—which present a cosmology different from earlier texts such as Lagadha’s Vedanga Jyotisha. He also had a verse to calculate duration of the planetary revolutions during a mahayuga is given as 4.32 million years.
- Ganitapada (33 verses): covering mensuration (kṣetra vyāvahāra), arithmetic and geometric progressions, gnomon / shadows (shanku-chhAyA), simple, quadratic, simultaneous, and indeterminate equations (kuTTaka)
- Kalakriyapada (25 verses): different units of time and a method for determining the positions of planets for a given day, calculations concerning the intercalary month (adhikamAsa), kShaya-tithis, and a seven-day week with names for the days of week.
- Golapada (50 verses): Geometric/trigonometric aspects of the celestial sphere, features of the ecliptic, celestial equator, node, shape of the earth, cause of day and night, rising of zodiacal signs on horizon, etc. In addition, some versions cite a few colophons added at the end, extolling the virtues of the work, etc.
Later on Pañcasiddhāntikā of Varāhamihira summarizes the five known Indian astronomical schools of the sixth century. Varāhamihira has also written some classic Jyotisa texts and we shall study them in future course of years.
The main texts upon which classical Indian astrology is based are early medieval compilations, notably the Bṛhat Parāśara Horāśāstra by Maharishi Parashara and Sārāvalī by Kalyāṇavarman. The Horashastra as it is commonly called is a composite work of approximately 71 chapters and is base to every Jyotiṣa and tradition across India and Jyotiṣa world.
