Your own pain is involuntary; you feel overwhelmed and have no control. When feeling the pain of others, there is an element of discomfort, but there also is a level of stability because you are voluntarily accepting pain. It gives you a sense of confidence.
Dalai LamaA mind that is characterized by unrest will not be tranquil even in the presence of great calm.
Dalai LamaIf I am only happy for myself, many fewer chances for happiness. If I am happy when good things happen to other people, billions more chances to be happy!
Dalai Lama
