The goal of Buddhism is non-existence, true death of the soul, or "enlightenment" also known as "nirvana". Taoism is on the other hand trying to give people immortality in this world. So called Zen-Buddhism combines Tao with Buddhism and in it emptiness is worshipped, and the so-called samurai, ronin and ninja pull energy out of the nothingness, the void, emptiness. The samurai think they are already dead. The so-called Japanese "samurai" code of honor and culture combines Zen-Buddhism with some Medieval Japanese ideals.
