Prem Prakash said this quote

I am fond of reminding my yoga students of the saying “It takes one to know one” when they become lost I condemnation and judgment of others. The world that we perceive is a reflection of our own states of mind and reveals our own level of consciousness. The world is little more than a Rorschach blot in which we see our own desire systems projected. We see what we want to see. (116)
