I'm just going to lift this straight from Windz's blog
There is nothing either good or bad. But thinking makes it so.
There is no need to be sad as there is no reason to be so.
There is no need to be happy as there is no cause for it.
There is no good nor bad in this world, because everything is relative.
There is no need for feelings, since feelings are unnecessary. An integral part of human beings that causes irrationality.
There is no need to think, since thinking will only add to our woes. It causes the good and bad to be defined, and makes us miserable when there are standards we cannot meet.
There is nothing either good or bad. But thinking makes it so. So why think? Why feel? Why be happy? Why be sad?
Who still remembers 勇士之城 (aka Takeshi's castle) from long long ago? Go youtube and search for it: lots of cool highlight clips from the UK translation.
