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 LamaPeace must first be developed within an individual. And I believe that love, compassion, and altruism are the fundamental basis for peace. Once these qualities are developed within an individual, he or she is then able to create an atmosphere of peace and harmony. This atmosphere can be expanded and extended from the individual to his family, from the family to the community and eventually to the whole world.
Dalai LamaThe more you think about your own self, the more self-centred you are, the more trouble even small problems can create in your mind. The stronger your sense of 'I', the narrower the scope of your thinking becomes; then even small obstacles become unbearable. On the other hand, if you concern yourself mainly with others, the broader your thinking becomes, and life's inevitable difficulties disturb you less.
Dalai LamaAll good qualities must be sown and cultivated. We canโt expect to change overnight from an ordinary person into one with high realizations.
