It is our collective and individual responsibility to preserve and tend to the environment in which we all live.
Dalai LamaExternal circumstances can contribute to one's happiness and well-being, but ultimately happiness and suffering depend on the mind.
Dalai LamaMisunderstanding may arise by confusing the Buddhist and scientific definitions of death. Within the scientific system you spoke quite validly of the death of the brain and the death of heart. Different parts of the body can die separately. However, in the Buddhist system, the word death is not used in that way. You'd never speak of the death of a particular part of the body, but rather of the death of an entire person. When people say that a certain person died, we don't ask, "Well, which part died?"
Dalai LamaIf there is no solution to the problem then don't waste time worrying about it. If there is a solution to the problem then don't waste time worrying about it.
