Once, Mrs. Tarkhad was staying in a certain house in Shirdi. At noon, meals were ready and dishes were being served, when a hungry dog turned up there and began to cry. Mrs. Tarkhad got up at once and threw a piece of bread, which the dog gulped with great relish. In the afternoon, when she went to the Masjid and sat at some distance, Sai Baba said to her, "Mother, you have fed Me sumptuously up to my throat, My afflicted pranas (life-forces) have been satisfied. Always act like this, and it will stand you in good stead. Sitting in this Masjid I shall never, never speak untruth. Take pity on Me like this. First give bread to the hungry, and then eat yourself. Note this well". At first she could not understand the meaning of what Baba had said. So she replied, "Baba, how could I feed You? I am myself dependent on others and take my food from them on payment". Then Baba replied, "Eating that lovely bread I am heartily contended and I am still belching. The dog which you saw before meals and to which you gave the piece of bread is one with Me, so also other creatures (cats, pigs, flies, cows etc.) are one with Me. I am roaming in their forms. He who sees Me in all these creatures is My beloved. So abandon the sense of duality and distinction, and serve Me, as you did today".
