I follow one site "www.devdutt.com", this is a part of one of the article from this site...

Dharma is that which makes human divine - our ability to say no to the beast within us, our ability to renounce the law of the jungle. The law of the jungle, that might is right, is acceptable for animals - but when humans follow it and dominate the weak, they subscribe to adharma. From the desire to dominate comes greed, the insatiable urge for power, for land, from the desire to dominate comes the desire to win, even in a gambling match, from the desire to dominate comes the willingness to wager one’s brothers and one’s wife. From adharma comes righteous indignation - the desire to impose one’s will on others.

Dharma is about listening, not speaking; dharma is about giving, not taking; dharma is about helping the helpless; dharma is about affection, not domination. Dharma happens when hungry men share their food. Gandhari’s children died because they refused to share their land. Draupadi’s children died because she could not forgive. So long as we refuse to share, so long as we refuse to forgive, so long as we find excuses to justify our greed, war will happen and heroes will never find peace.

Vyasa raises both his hands and shouts, “Follow dharma and there will be peace in the world. True peace, not peace born by dominating the other.” Is anyone listening?
