To me it seems that to give happiness is a far nobler goal that to attain it: and that what we exist for is much more a matter of relations to others than a matter of individual progress: much more a matter of helping others to heaven than of getting there ourselves.
The sage does not hoard. The more he helps others, the more he benefits himself, The more he gives to others, the more he gets himself. The Way of Heaven does one good but never does one harm. The Way of the sage is to act but not to compete.
Every single being, even those who are hostile to us, is just as afraid of suffering as we are, and seeks happiness in the same way we do. Every person has the same right as we do to be happy and not to suffer. So let's take care of others wholeheartedly, of both our friends and our enemies. This is the basis for true compassion.
