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.
Great Powers of falling wave and wind and windy fire,
With your harmonious choir
Encircle her I love and sing her into peace,
That my old care may cease.
When the only bond between close friends is attachment, then even a minor issue may cause one's projections to change. As soon as our projections change, the attachment disappears, because that attachment was based solely on projection and expectation. It is possible to have compassion without attachment, and similarly, to have anger without hatred.

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.
Anger cannot be overcome by anger. If someone is angry with you, and you show anger in return, the result is a disaster. On the other hand, if you control your anger and show its opposite - love, compassion, tolerance and patience - not only will you remain peaceful, but the other person's anger will also diminish.
Criminals, people who commit crimes, usually society rejects these people. They are also part of our society. Give them some form of punishment to say they were wrong, but show them they are part of society and can change. Show them compassion.
As people alive today, we must consider future generations: a clean environment is a human right like any other. It is therefore part of our responsibility toward others to ensure that the world we pass on is as healthy, if not healthier, than we found it.
We live in a culture that discourages empathy. A culture that too often tells us our principle goal in life is to be rich, thin, young, famous, safe, and entertained.
