The Guru in the Hindu tradition is looked upon as an embodiment of God himself. For, it is through his grace and guidance that one reaches the highest state of wisdom and bliss. "My salutations to the Guru who is Brahma, Vishnu and Maheswara. The Guru is Parabrahma incarnate".

Gururbrahmaa gururvishnuh gururdevo Maheswarah |
Guruh-saakshaat parabrahma tasmai shrigurave namah ||
