The 18th chaupai of the Hanuman Chalisa encodes the precise distance from Earth to the Sun — the same figure NASA only calculated in the 20th century as one Astronomical Unit.
This multi-speaker session organised by the Draupadi Foundation systematically presents Jyotish as a rigorous science — not the prediction-focused Hora branch most people associate with astrology, but the foundational Siddhan Jyotish: the mathematical astronomical treatises written by 18 Rishis including Surya Siddhanta, Agni Siddhanta, and Parashar Siddhanta. These texts provided the astronomical basis from which predictive astrology derives — a fact almost entirely unknown to modern audiences.
The Earth-Sun distance calculation from Yug Sahasra Yojan (units from Hanuman Chalisa) yields 15.36 crore kilometres — precisely the average of perihelion and aphelion distances now measured by NASA as 1 AU = 15 crore km. The session argues this is not coincidence but systematic astronomical knowledge embedded in devotional literature to ensure its preservation across millennia. The deeper case being made: Jyotish is gadhitagya — mathematical knowledge — not superstition.
