Guru Stotram 11

Quote

“Na Guror-adhikam tattvam na Guror-adhikam tapah
Tattva-gyanat-param nasti tasmai Shri Gurave Namah”

There is no higher truth than the Guru, no higher penance than (service to) the Guru, and there is nothing higher than Realisation of the Knowledge of the truth imparted by the Guru. My salutations to that glorious Guru, who is himself that very timeless truth (and who has taken up a form to bless his disciples like us with real knowledge).

Who is a Guru?

Quote

Who is the Guru Mr. Evans-Wentz continued another day: “May one have more than one spiritual master?”

M.: Who is a Master? He is the Self after all. According to the stages of the development of the mind the Self manifests as the Master externally. The famous ancient saint Avadhuta said that he had more than 24 Masters. The Master is one from whom one learns anything. The Guru may be sometimes inanimate also, as in the case of Avadhuta. God, Guru and the Self are identical.

A spiritual-minded man thinks that God is all-pervading and takes God for his Guru. Later, God brings him in contact with a personal Guru and the man recognises him as all in all. Lastly the same man is made by the grace of the Master to feel that his Self is the Reality and nothing else. Thus he finds that the Self is the Master.
