Foundation — Astronomical and Numerical Basis

5 modules · ≈6.5 hours · Introduction
अथ ज्योतिषं वक्ष्यामि सर्व-शास्त्र-समन्वितम्।Now I shall speak of jyotiṣa, comprehensive with all the śāstras.

If you have no prior background in jyotiṣa, start here. This path establishes the geometric and numerical foundation — the celestial objects, their divisions, and the time-grid in which interpretation happens. We do NOT make predictions here; we equip you to understand what every other page in the engine is computing.
