Ultimately, the reason why love and compassion bring the greatest happiness is simply that our nature cherishes them above all else. The need for love lies at the very foundation of human existence.
Dalai LamaPeace and the survival of life on earth as we know it are threatened by human activities which lack a commitment to humanitarian values. Destruction of nature and nature's resources result from ignorance, greed and lack of respect for the earth's living things.
Dalai LamaAccording 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.
