When a planet is far from its Sighra-uchcha (conjunction), it is pulled backward... and becomes retrograde.
Modern Technical Commentary:
The physical model of retrograde motion. The Siddhanta describes planets as being pulled by 'reins of air' (vayu-rashmi) attached to their conjunction points. When the planet is far enough (near opposition), this pull reverses its apparent direction.

Identifies when the planet reaches the 'turning points'
in its synodic cycle relative to the Sighrocca.
Determine if a planet is in Retrograde (Vakra) motion.
