Compassion is best described as an understanding of the emotional state of another; not to be confused with empathy. Compassion is often combined with a desire to alleviate or reduce the suffering of another; to show special kindness to those who suffer. Compassion may lead one to feel empathy with another person. Compassion is often characterized through actions, wherein a person acting with compassion will seek to aid those they feel compassionate for.
Compassionate acts are generally considered those which take into account the pain of others and attempt to alleviate that pain. In this sense, the various forms of the Golden Rule are in part based on the concept of compassion, if also on the concept of empathy.
I have benn told I have too much compassion. I feel the pain of everyone and at times sacrifice too much to help others.
