Well... thats one of the many things in common between shamanism and christianism that i found... My signature, that was said by Don Juan, an indian shaman, is a "nicer" way to say the same thing that "dont cast your pearls before swine"... Both talk about the uselessness of trying explain some knowledge to someone who can not understand it.
As i may change my sig any day, ill quote it here, so this post will not become useless if i change it later:

"Everything we do, everything we are, rests on our personal power. If we have enough of it, one word uttered to us might be sufficient to change the course of our lives. But if we don't have enough personal power, the most magnificent piece of wisdom can be revealed to us and that revelation won't make a damn bit of difference." Don Juan Matus - Tales of Power

Anyone who had some discussion about weed with somebody who never smoked will understand the point perfectly... :jointsmile:
