Varahamihira, Brihat Samhita
Definition
Varahamihira, Brihat Samhita is an astrological source represented here through cited material on agriculture, observation, solar ingress, architecture, and astronomy.

What this work covers
The cited material covers agriculture, observation, solar ingress, architecture, and astronomy.
The astrologer is expected to distinguish several time measures and reconcile disagreements among astronomical systems by comparing accurate calculation with direct shadow- and water-instrument observation; eclipse and planetary phenomena are likewise to be computed before judgment.
Crop forecasting is anchored to the Sun's ingress into Scorpio for summer crops and Taurus for autumn crops, then conditioned by benefic occupation or aspect of the ingress figure rather than by an isolated planet placement.
The time-of-fruition chapter assigns different default delay bands to planetary transits, eclipses, comets, halos, rainbows, twilight phenomena, and cloud forms instead of treating every observed sign as immediate.
Scope and limitations
