When a person is in a miserable situation, then, yes, it is difficult to develop genuine compassion toward others. That's why I find it difficult to say to poor people, "Please have compassion toward millionaires." That's not easy.
In harmony with the Tao, the sky is clear and spacious, the earth is solid and full, all creature flourish together, content with the way they are, endlessly repeating themselves, endlessly renewed. When man interferes with the Tao, the sky becomes filthy, the earth becomes depleted, the equilibrium crumbles, creatures become extinct. The Master views the parts with compassion, because he understands the whole. His constant practice is humility. He doesn't glitter like a jewel but lets himself be shaped by the Tao, as rugged and common as stone.
Look upon him who shows you your faults as a revealer of treasure: seek his company who checks and chides you, the sage who is wise in reproof: it fares well and not ill with him who seeks such company.
I think there is a complicated side effect to overcoming evil in that we are forever changed by it. I think after we ingest some of the cruelty of the world, it takes years off of our lives, but it also gives us wisdom and a little grace, hopefully a sense of compassion.
Without religion, also there is a way, it could be this way, through education, through scientific findings, then you get conviction. Not necessarily really love other, but for their own interest they are showing love, compassion to other like that.
Understand the suffering of worldly existence.
Abandon its causes of ignorance and selfishness.
Practice the path of meditation and compassion.
Awaken from suffering within Great Peace.
The wounded surgeon plies the steel
That questions the distempered part;
Beneath the bleeding hands we feel
The sharp compassion of the healer's art
Resolving the enigma of the fever chart.
The compassion we feel normally is biased and mixed with attachment. Genuine compassion flows towards all living beings, particularly your enemies. If I try to develop compassion towards my enemy, it may not benefit him directly, he may not even be aware of it. But it will immediately benefit me by calming my mind. On the other hand, if I dwell on how awful everything is, I immediately lose my peace of mind.
When faith is completely replaced by creed, worship by discipline, love by habit; when the crisis of today is ignored because of the splendors of the past; when faith becomes an heirloom rather than a living fountain; when religion speaks only in the name of authority rather than with the voice of compassion, its message becomes meaningless.
Be a good human being, a warm-hearted affectionate person. That is my fundamental belief. Having a sense of caring, a feeling of compassion will bring happiness of peace of mind to oneself and automatically create a positive atmosphere.
In the beginning, compassion is like the seed without which we cannot have any fruit; in the middle, compassion is like water to nourish the see we have planted; in the end, compassion is like the warmth of the sun that brings the fruit to ripening.
