Guru mahima refers to the glory or greatness of the master. But, the guru's exalted status cannot easily be fathomed by those who have not come in contact with one. It is said, the Upanishads reveal their meaning to that student who has the same supreme devotion for the guru as he has for God. They state that even if a person is totally ignorant spiritually, but serves an enlightened master with complete sincerity and dedication, he will be liberated. Such is guru mahima.
