Sensory experience does not offset the intense pain or pleasure we feel on a mental level; it may distract us, but doesn't overcome it. On the other hand, if we have peace of mind, even negative experiences do not upset us. Peace of mind is also good for our physical health. Medical experts have found that anger, hatred and fear eat into our immune system. Being calm and relaxed is better for our physical well-being.
Dalai LamaIf you wish to experience peace, provide peace for another. If you wish to know that you are safe, cause another to know that they are safe. If you wish to better understand seemingly incomprehensible things, help another to better understand. If you wish to heal your own sadness or anger, seek to heal the sadness or anger of another.
Dalai Lama
