I have watched his tapes "The Flowering of Human Consciousness" and thought they were really powerful. I have heard that very enlightened persons can impart a portion of that higher vibration on a student just by being in their presence (something to that effect, I don't really have the language for it), and I have to say I think something was directly instilled into my consciousness through those videos, because a very positive transformation began to take place for me immediately after that, without my even trying.
