Yoga and Ayurveda
Yoga is one among the sad-darshana (six-views or six insights) which are at the core of Indian philosophy. Others in the list are nyaya, vaisheshika, sankhya, mimamsa and vedanta. Concepts of yoga are found scattered in the four vedas, and it is Patanjali who compiled this information in the form of yoga sutras. He came up with concise and terse aphorisms (sutras), 196 in number, expounding the path of yoga.
Over a period of time several commentaries were written on these sutras. Till date a significant number of texts have been written on yoga, but authority remains with the yoga sutra of Patanjali.
