Misunderstanding 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 science proves some belief of Buddhism wrong, then Buddhism will have to change. In my view, science and Buddhism share a search for the truth and for understanding reality. By learning from science about aspects of reality where its understanding may be more advanced, I believe that Buddhism enriches its own worldview.
Dalai LamaA lot of problems we are facing, essentially, man made problem. Own creation. Not due to lack of intelligence.
Dalai LamaThe more contact we have with one another and the more we come to understand each other's values, the greater will be our mutual respect.
Dalai LamaYou need self-confidence and determination: feeling depressed and losing hope will never really help to correct any situation.
Dalai LamaOne of the most effective ways to overcome anxiety is to try to shift the focus of attention away from self and toward others. When we succeed in this, we find that the scale of our own problems diminishes. This is not to say we should ignore our own needs altogether, but rather that we should try to remember others' needs alongside our own, no matter how pressing ours may be
