Hatha

Etymologically “force” or “violence” (in the sense of intensity). According to the Hatha Yoga Pradipika, it represents the union of Ha (sun/pingala) and Tha (moon/ida).

A system of yoga that uses specific bodily techniques as preparation for Raja Yoga. It is not a “physical” yoga in the modern sense, but a precise method for balancing pranic energies and preparing the body for deep meditative states.
