In the old times there was the Laughter of The Gods. Mighty fine weapon against evil. Whoever terrorizes anyone or wields power, looses all might over other people when they laugh into his face...
Charlie Chaplin understood this. His parody on Adolf Hitler is perfect. Hitler had a demonic charisma, people got hysteric when he spoke. But whenever I see docu about Hitler in TV, Charlie Chaplin shouts "Shtonk!"
If every politician and every fanatic leader and every general and every big fat bully with no brain had a small man standing behind him, grimacing and shouting "Shtonk!" There would be a lot of less trouble in the world.
Personally, I find nothing in far-eastern lores. But Swami Beyondananda for sure has the better weapon against Al Khaida and Taliban than Prez. Bush.
By the way, did you know that not so long ago ritual laughter was practiced in christian churches, expecially on easter morning?
