Philosophical understanding of Yoga in the Vedas Upanisads Buddhism Jainism Patanjal Yoga and Integral Yoga

Introduction Yoga tradition is very ancient. In Pāṇini, the word 'Yoga' is derived from the root 'Yuj', in the sense of samādhi (concentration) and 'Yujir' in sense of joining or connecting. According to Pāṇini, 'Yogi' means a man who practices religious austerities. In early 1920's, during excavation of Indus civilization (about 3000BC), traces of early Yoga were found in Indus cities.
