The Brihat Parashara Hora Shastra (Sanskrit: à ¤¬à ¥Âà ¤¹à ¤¤à ¥ à ¤ªà ¤°à ¤¾à ¤¶à ¤° à ¤¹à ¥Âà ¤°à ¤¾ à ¤¶à ¤¾à ¤¸à ¥Âà ¤¤à ¥Âà ¤°; IAST: '; abbreviated to BPHS) is the most comprehensive extant à ÂÃÂstra on Vedic natal astrology, in particular the Horàbranch (predictive astrology, e.g. horoscopes). Though ascribed to Mahará¹£i ParÃÂà Âara, the origin and date of the original composition is unknown. The most popular version of the BPHS consists of 97 chapters, a 1984 translation by R. Santhanam.

The Jyotiá¹£a - Vedic Astrology - is one of the VedÃÂá¹ ga or six disciplines linked with the Vedas to support Vedic rituals. The three branches of Jyotiá¹£a are:
The Bá¹Âhat ParÃÂà Âara Horàà ÂÃÂstra is concerned with the predictive branch of HorÃÂ, used, for example, to determine the appropriate and most auspicious times for various events and ceremonies (i.e. depending on the anticipated planetary and star movements and positions).
J. Gonda states that at 'some time after 600 [<nowiki/>C.E.] was written the purva-khanda of what was to become known as the Brhatparasarahora [Brihat Parashara Hora Shastra], ascribed to Parashara. it is deeply indebted to the [Brhajjataka of Varahamihira]; it has also borrowed two verses from Sphujidhvaja... and its existence is presupposed by the author of the uttara-khanda, which was commented on by Govindasvamin in ca. 850 [C.E.]. Therefore, the purva-khanda must have been written between ca. 600 and 750... but before 800'.
Additionally Bhaá¹Âá¹Âotpala (circa 900 C.E.) was a Vedic astrologer that 'in his commentaries he wrote that though he had heard of [the] Bá¹Âhat ParÃÂà Âara Horàà ÂÃÂstra, he had never seen it. Thus we know it was lost for at least nine hundred years, until new manuscripts emerged from the early 20th century (see below).
As such, there are doubts in regards to the authenticity of various manuscripts of the Bá¹Âhat ParÃÂà Âara Horàà ÂÃÂstra (BPHS) that emerged centuries later. One concern raised is the apparent admission by Sitram Jha in his 1944 publication of the BPHS that he changed and removed elements of the manuscript. Another concern raised by Vedic Astrologers such as Shyamasundara Dasa 'that casts doubt on the veracity of the modern BPHS is the complete lack of any ancient commentary on the text. The oldest commentary known to me is that of Devacandra Jha's Hindi commentary from the first half of the 20th century, that is, less than 100 years old'.
According to R. Santhanam and J. Gonda, the following are the modern translations (and manuscripts) of the Bá¹Âhat ParÃÂà Âara Horàà ÂÃÂstra (BPHS):
