The yogic teachings found in the above-mentioned Rig-Veda and the other three ancient hymnodies are known as Vedic Yoga. The Sanskrit word veda means "knowledge," while the Sanskrit term rig (from ric) means "praise." Thus the sacred Rig-Veda is the collection of hymns that are in praise of a higher power. This collection is in fact the fountainhead of Hinduism, which has around one billion adherents today. You could say that the Rig-Veda is to Hinduism what the Book of Genesis is to Christianity.
The other three Vedic hymnodies are the Yajur-Veda ("Knowledge of Sacrifice"), Sama-Veda ("Knowledge of Chants"), and Atharva-Veda ("Knowledge of Atharvan"). The first collection contains the sacrificial formulas used by the Vedic priests. The second text contains the chants accompanying the sacrifices. The third hymnody is filled with magical incantations for all occasions but also includes a number of very powerful philosophical hymns. It is connected with Atharvan, a famous fire priest who is remembered as having been a master of magical rituals. These hymnodies can be compared to the various books of the Old Testament. It is clear from what has been said thus far that Vedic Yoga-which could also be called Archaic Yoga-was intimately connected with the ritual life of the ancient Indians.It revolved around the idea of sacrifice as a means of joining the material world with the invisible world of the spirit. In order to perform the exacting rituals successfully, the sacrificers had to be able to focus their mind for a prolonged period of time. Such inner focusing for the sake of transcending the limitations of the ordinary mind is the root of Yoga.
When successful, the Vedic yogi was graced with a "vision" or experience of the transcendental reality. A great master of Vedic Yoga was called a "seer"-in Sanskrit rishi. The Vedic seers were able to see the very fabric of existence, and their hymns speak of their marvelous intuitions, which can still inspire us today.
