Brihat Parashara Hora Shastra

The Brihat Parashara Hora Shastra, abbreviated BPHS, is the most comprehensive and most-cited classical text in Vedic astrology. It is traditionally attributed to Maharshi Parashara, the rishi-author of several other Vedic-tradition works, though scholarly opinion on its actual date of composition ranges across several centuries. The surviving recension is generally dated to the medieval period; its underlying material is older.

BPHS covers, across nearly 100 chapters: the calculation of planetary positions, the meaning of the twelve signs and houses, planetary significations, the divisional charts (vargas), yogas (specific planetary combinations), the Vimshottari and other dasha systems, and traditional remedial measures.

BPHS functions as a shared reference point across most mainstream Jyotisha traditions. Citing it with chapter and shloka — keyed to the Santhanam English edition — is how we keep our interpretations auditable rather than asserted.

Used on SahiKundli for: lagna-card citations on every chart, planet-in-house readings, yoga detection, and dasha interpretations.
