I have found that the definition of TRUTH is those things which are, and which will NOT change, and which defintely will happen, independent of the belief or philosophies of man, or our willingness to accept it when it is presented before us. I also find that the more we learn about others, the better able we are to discern truth and falsehood in what we already know ourselves. That's not something from Buddah or anything; it's just an eternal principle.
