I want to show that there are indeed some universal ethical principles which could help everyone to achieve the happiness we all aspire to.

Sensory experience does not offset the intense pain or pleasure we feel on a mental level; it may distract us, but doesn't overcome it. On the other hand, if we have peace of mind, even negative experiences do not upset us. Peace of mind is also good for our physical health. Medical experts have found that anger, hatred and fear eat into our immune system. Being calm and relaxed is better for our physical well-being.

Happiness mainly comes from our own attitude, rather than from external factors.

Peace, in the sense of the absence of war, is of little value to someone who is dying of hunger or cold. It will not remove the pain of torture inflicted on a prisoner of conscience. It does not comfort those who have lost their loved ones in floods caused by senseless deforestation in a neighboring country. Peace can only last where human rights are respected, where the people are fed, and where individuals and nations are free.

For Tibetans, the real strength of our struggle is truth - not size, money, or expertise.

The affection is mainly biological factor. Then further sort of strengthening, that religion helps.

I am basically optimistic.
