Patanjali 
Yoga Aphorisms of Patanjali 

The Yoga Sutras of Patanjali are a collection of 196 Sanskrit sutras (aphorisms) on the theory and practice of yoga. The Yoga Sutras were compiled prior to 400 CE by the sage Patanjali in India who synthesized and organized knowledge about yoga from much older traditions. The Yoga Sutras of Patanjali was the most translated ancient Indian text in the medieval era.Before the 20th century, history indicates that the medieval Indian yoga scene was dominated by the various other texts such as the Bhagavad Gita and the Yoga Vasistha, texts attributed to Yajnavalkya and Hiranyagarbha, as well as literature on hatha yoga, tantric yoga and Pashupata Shaivism yoga rather than the Yoga Sutras of Patanjali.Yoga tradition holds the Yoga Sutras of Patanjali to be one of the foundational texts of classical Yoga philosophy.
