At the beginning of this century, people never questioned the effectiveness of war, never thought there could be real peace. Now, people are tired of war and see it as ineffective in solving anything.
Buddha was speaking about reality. Reality may be one, in its deepest essence, but Buddha also stated that all propositions about reality are only contingent. Reality is devoid of any intrinsic identity that can be captured by any one single proposition - that is what Buddha meant by "voidness." Therefore, Buddhism strongly discourages blind faith and fanaticism.
Some people automatically associate morality and altruism with a religious vision of the world. But I believe it is a mistake to think that morality is an attribute only of religion. We can imagine two types of spirituality: one tied to religion, while the other arises spontaneously in the human heart as an expression of love for our neighbors and a desire to do them good.
It is important to reflect on the kindness of others. Every aspect of our present well-being is due to others' hard work. The buildings we live and work in, the roads we travel, the clothes we wear, and the food we eat, are all provided by others. None of them would exist but for the kindness of so many people unknown to us.
I believe that the very purpose of life is to be happy. From the very core of our being, we desire contentment. In my own limited experience I have found that the more we care for the happiness of others, the greater is our own sense of well-being.
The real troublemakers are anger, jealousy, impatience, and hatred. With them, problems cannot be solved. Though we may have temporary success, ultimately our hatred or anger will create futher difficulties. Anger makes for swift solutions. Yet, when we face problems with compassion, sincerity, and good motivation, our solutions may take longer, but ultimately they are better.
We need a sense of the oneness of the 7 billion human beings alive today. When I meet people, I don't think about being different from them, about being Tibetan, Buddhist or even the Dalai Lama. I only think about being a human being. We all share the potential for positive and negative emotions, yet one of our special qualities is our human mind, our intelligence. If we use it well we'll be successful and happy.
