According to the Zen philosophy, we should learn how "to go with the flow" be passive, and never resist whatever life through in your face (i dont know how can this be reconciled with the law of Karma as explained above) to explain my point a bit further please read the following story:
The master said, "That is his problem, not mine." !!!! So what all of this is about? being self-centred? is this the way to make the world a better place?
Great!! so if the Buddha sees someone suffering why should he bother helping? to help others we should be motivated, we should have some sort of desire, isnt it.
One of my favourite movies is "Samsara" its about the spiritual jounry of a buddhist monk. In the movie he recieved a letter his teacher asking him "what is more important: to satisy one thousand desires or conquering just one!" from my understanding (and please correct me if i am wrong, the only desire a buddist would have is LIBERATION from all desires!!! so if i liberate myslef from all desires (which sounds good to me) and i become free, why should i bother doing anything in life!! I would just sit there doing nothing (a complete dispassion, no attachement whatsoever) and wait for death to come and wish that i break out of the cycle of death and never come back to this miserable world.
One last point is in relation to "living in the presnt moment" and in the "here and now" what buddhism say about planning? is planning for the future a bad thing according to buddism?
