Yoga in its origin is a native Indian psycho-spiritual craft, used for personal transformation and to alleviate suffering in the human condition. In a sense, yoga is pan Indian in that it is not restricted to any particular religion or sect, region or location. While it is central to Brahmanism, Buddhists as well as Jainas have practised some kind of yoga. “Yoga constitutes a characteristic dimension of Indian Thought,” concludes Mircea Eliade (1969) in his influential book Yoga: Immortality and Freedom, “to such a point that wherever Indian religion and culture have made their way, we also find a more or less pure form of yoga” (p.359). There are good reasons to think that yoga is a pre-Aryan native Indian practice(s) that was later assimilated into the Vedic tradition (Narain, 1980). References to yoga practices date back to at least Upaniṣadic times. Explicit mention of yoga occurs in Maitrāyaṇī, Śvetāśvatara and Kaṭtha Upaniṣads among others. Yoga has now acquired pan human relevance going beyond the Indian community. For example, it is today a billion dollar business in the United States of America.
Etymologically, as is well-known, the word “yoga” is derived from the root “yuj,” which means “to bind” or “to yoke”. Inasmuch as there is ambiguity as to what precisely are the things to bind or unify, a wide variety of forms of yoga came into existence. Many of these are unsystematic and some are mystical and esoteric (Eliade, 1969). However, three levels of binding can be discerned from the practices. The first level is connecting the body and the mind.
