When something needs to be done in the world to rectify the wrongs, if one is really concerned with benefiting others, one needs to be engaged, involved. This is action out of compassion.
I don't try to imagine a personal God; it suffices to stand in awe at the structure of the world, insofar as it allows our inadequate senses to appreciate it.
Learn from the birds what food the thickets yield;
Learn from the beasts the physic of the field;
The arts of building from the bee receive;
Learn of the mole to plow, the worm to weave.
No man is an island, entire of itself; every man is a piece of the continent, a part of the main. If a clod be washed away by the sea, Europe is the less, as well as if a promontory were, as well as if a manor of thy friend's or of thine own were: any man's death diminishes me, because I am involved in mankind, and therefore never send to know for whom the bells tolls; it tolls for thee.
It is important to have determination and optimism and patience. If you lack patience, even when you face some small obstacle, you lose courage. There is a Tibetan saying, "Even if you have failed at something nine times, you have still given it effort nine times." I think that's important. Use your brain to analyze the situation. Do not rush through it, but think. Once you decide what to do about that obstacle, then there's a possibility that you will achieve your goal.
You must not hate those who do wrong or harmful things; but with compassion, you must do what you can to stop them — for they are harming themselves, as well as those who suffer from their actions.
