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 LamaIn Buddhism, both learning and practice are extremely important, and they must go hand in hand. Without knowledge, just to rely on faith, faith, and more faith is good but not sufficient. So the intellectual part must definitely be present. At the same time, strictly intellectual development without faith and practice, is also of no use. It is necessary to combine knowledge born from study with sincere practice in our daily lives. These two must go together.
Dalai LamaPeace does not mean an absence of conflicts; differences will always be there. Peace means solving these differences through peaceful means; through dialogue, education, knowledge; and through humane ways.
Dalai LamaI find hope in the darkest of days, and focus in the brightest. I do not judge the universe.
Dalai LamaAlthough you can find certain differences among the Buddhist philosophical schools about how the universe came into being, the basic common question addressed is how the two fundamental principles-external matter and internal mind or consciousness-although distinct, affect one another. External causes and conditions are responsible for certain of our experiences of happiness and suffering. Yet we find that it is principally our own feelings, our thoughts and our emotions, that really determine whether we are going to suffer or be happy.
Dalai LamaIt is important that when pursing our own self-interest we should be 'wise selfish' and not 'foolish selfish'. Being foolish selfish means pursuing our own interests in a narrow, shortsighted way. Being wise selfish means taking a broader view and recognizing that our own long-term individual interest lies in the welfare of everyone. Being wise selfish means being compassionate.
