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.
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.
If indeed the qualities such as love, patience, tolerance, and forgiveness are what happiness consists in, and if it is also true that compassion, defined as concern for others, is both the source and the fruit of these qualities, then the more we are compassionate, the more we provide for our own happiness.
Every religion emphasizes human improvement, love, respect for others, sharing other people's suffering. On these lines every religion had more or less the same viewpoint and the same goal.
Most governments are pragmatic, most people are logical. There are pockets of extremism in Israel, in the U.S. and in the Muslim world. But we have to fight them with reason, with logic and with compassion.
Let us have compassion for those under chastisement. Alas, who are we ourselves? Who am I and who are you? Whence do we come and is it quite certain that we did nothing before we were born? This earth is not without some resemblance to a gaol. Who knows but that man is a victim of divine justice? Look closely at life. It is so constituted that one senses punishment everywhere.
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.
True happiness comes from having a sense of inner peace and contentment, which in turn must be achieved by cultivating altruism, love and compassion, and by eliminating anger, selfishness and greed.
