According to Buddhist psychology most of our troubles stem from attachment to things that we mistakenly see as permanent.
Dalai LamaPeople often expect the other person to respond first in a positive way, instead of taking the initiative to create that possibility. I feel that's wrong; it can act as a barrier that just promotes a feeling of isolation from others. To overcome feelings of isolation and loneliness, your underlying attitude makes a tremendous difference - approaching others with the thought of compassion in your mind is the best way.
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?"
