In this century we have made remarkable material progress, but basically we are the same as we were thousands of years ago. Our spiritual needs are still very great.
According to accounts of the Buddha's life, it would seem that he had a very deep relationship with nature. He was not born in the royal palace but in a park, under a sala tree. He attained complete enlightenment under the bodhi tree and left this earth to enter Parinirvana, again, between three sala trees. It would seem that the Buddha was very fond of trees.
The question of real, lasting world peace concerns human beings, so basic human feelings are also at its roots. Through inner peace, genuine world peace can be achieved. In this the importance of individual responsibility is quite clear; an atmosphere of peace must first be created within ourselves, then gradually expanded to include our families, our communities, and ultimately the whole planet.
Some people get the impression that Buddhism talks too much about suffering. In order to become prosperous, a person must initially work very hard, so he or she has to sacrifice a lot of leisure time. Similarly, the Buddhist is willing to sacrifice immediate comfort so that he or she can achieve lasting happiness.
All religion teaches the virtues of love, altruism and patience, while showing us how to discipline and transform ourselves to achieve inner peace and a kind heart. Therefore, they are worthy of our respect.
