BPHS – The Foundational Text of Vedic Astrology

The Brihat Parashara Hora Shastra (BPHS) is the single most important text in Parashari Jyotish. Attributed to Maharishi Parashara – the father of Vyasa, who composed the Mahabharata – it is a comprehensive encyclopedia of predictive astrology spanning 97 chapters and roughly 4,000 verses in its most complete recensions.

The text is structured as a dialogue: the sage Parashara teaches his disciple Maitreya, who asks progressively deeper questions. This guru-shishya format mirrors the Upanishadic tradition and allows the text to build from foundational concepts (planetary nature, sign properties) to advanced techniques (conditional dashas, nabhasa yogas, remedial prescriptions).

Dating BPHS precisely is difficult. The core astronomical content may originate from 1500-1200 BCE, while later chapters on remedies and certain yoga combinations were likely added over centuries. What matters for practitioners is that the system works – and its internal consistency is remarkable for a text of such scope.
