If someone remains in a peaceful and tranquil state of mind, external surroundings can cause them only a limited disturbance.
Dalai LamaIf you wish to heal your own sadness or anger, seek to heal the sadness or anger of another. Those others are waiting for you now. They are looking to you for guidance, for help, for courage, for strength, for understanding, and for assurance at this hour. Most of all, they are looking to you for love.
Dalai LamaIf the mind is tranquil and occupied with positive thoughts, the body will not easily fall prey to disease
Dalai Lama
