Patanjali Yoga Sutras

The Patanjali Yoga Sutras is the foundational text of yoga, written by the father of yoga, the enlightened sage Patanjali. This esoteric yet highly practical text is based on Sankhya Yoga. It is said to date back to the 2nd century BC, although it is believed to be far more ancient. Patanjali Yoga Sutras emphasize the value of yoga as a lifestyle through ashtanga yoga (8-limbed yoga).
