An attitude of generosity, of fortitude in the presence of sorrow and loss, a spirit of enthusiasm to do good, to be of service to the best of one’s capacity – these build up the mind as well as the body. Practice the attitude of joy when others are joyful and of grief when others around you are grieved. Let your heart move in sympathy. But, the joy and grief have to be translated into service; they should not be mere emotions.
(From : Sai Veda, The Word of God, sayings of Bhagavan Sri Sathya Sai Baba)
