When you treat any one harshly, you are treating Me harshly. When you are insulting any one, you are insulting Me. Behave towards others as you wish them to behave towards you. It is the heart of stone that blinds the eye to the pain, that others endure. Learn to adjust your likes and dislikes to those of others, learn the gentle art of sacrifice and service.
(From : Sai Veda, The Word of God, sayings of Bhagavan Sri Sathya Sai Baba)
