Parashar21

Parashar21 is a deterministic Hindu Jyotisha (Vedic Astrology) engine built around the Swiss Ephemeris. Given the place, date, and time of birth, it computes planetary positions, houses, lords, aspects, conjucnts and dashas and other classical astrological parameters based on the principles of Maharishi Parashara.

The current generation of Parashar21 extends beyond chart computation by producing a structured semantic description of the horoscope. This machine-readable representation forms the bridge between deterministic astrological computation and modern Large Language Models (LLMs), enabling comprehensive, context-aware interpretations grounded in classical Jyotisha literature.

The guiding philosophy is simple:

Parashar21 performs the mathematics. The LLM performs the interpretation.

This hybrid neuro-symbolic architecture preserves the precision and repeatability of classical astrological computation while leveraging the reasoning capabilities of contemporary AI systems.

The overall architecture of the project is illustrated below.

For a detailed description of the system architecture, design rationale, and processing pipeline, see Architecture.md.
