Yoga Sutras of Patanjali

The Yoga Sutras of Patanjali succinctly outlines the art and science of Yoga meditation for Self-Realization. It is a process of systematically encountering, examining, and transcending each of the various gross and subtle levels of false identity in the mind field, until the jewel of the true Self comes shining through.

The Yoga Sūtras of Patañjali are 196 Indian sūtras (aphorisms) that constitute the foundational text of Ashtanga Yoga, also called Raja Yoga. In medieval times, Ashtanga Yoga was cast as one of the six orthodox āstika schools of Hindu philosophy.
The Yoga Sutras were compiled around 400 CE by Patañjali, taking materials about yoga from older traditions.Together with his commentary they form the Pātañjalayogaśāstra.
