Those who recognize the existence of suffering, its cause, its remedy, and its cessation, have fathomed the four noble truths. They will walk in the right path.
If there is suffering, then it's best to accept it, because it won't go away just because you pretend it's not there. If there is joy, then it's best to accept that too, even though you're afraid it might end one day.
It is important not to allow ourselves to be put off by the magnitude of others' suffering. The misery of millions is not a cause for pity. Rather it is a cause for compassion.
How is it possible that suffering that is neither my own nor of my concern should immediately affect me as though it were my own, and with such force that is moves me to action?
Ecology more important than saving animals from slavery??? Humans suffer the raping of the earth but animals suffer DOUBLY: the raping of the earth PLUS their own raping by humans. They are innocent/they are not the ones who raped the earth/they enrich it for us all from the tiniest microscopic beings to the largest ones.
