It does not matter whether you are a theist or atheist, what matters is sincerity, forgiveness, and compassion.
Dalai LamaOne scientist had discussions about love and compassion. Usually, he felt irritation. After our meeting, for some months, anger never come.
Dalai LamaThe rationale for loving others is the recognition of the simple fact that every living being has the same right to and the same desire for happiness, and not suffering, and the consideration that you as one individual are one life unit as compared with the mulititude of others in their ceaseless quest for happiness.
Dalai LamaHatred, jealousy and excessive attachment cause suffering and agitation. I feel compassion can help us overcome these disturbances and let us return to a calm state of mind. Compassion is not just being kind to your friend. That involves attachment because it is based on expectation. Compassion is when you do something good without any expectations - based on realizing that "the other person is also just like me".
