At The Table Of A Lover Of God

The disciple, who is fed at the table of a lover of God, has a clean and true spirit.
But those who are nourished by the hands of an imposter and a braggart, learning the science from them, become just like their teacher, contemptible and feeble, weak and unable to make up their minds about anything.
Fihi Ma fihi - Discourse 8, A. J. Arberry
