I cannot do anything without God's permission.
We regard Sai Baba as an incarnation of God but He always said that He was an obedient servant of God. Though an incarnation He showed the people the way, how to behave satisfactorily and carry out the duties of their respective stations in this life. He never emulated others in any way, nor asked others to have something done for Him. For Him, Who saw the Lord in all movable and immovable things of this world, humility was the most proper thing. None He disregarded or disrespected; for He saw Narayan (Lord) in all beings. He never said, "I am God," but that He was a humble servant and He always remembered Him and always uttered - "Allah Malik" (God is the sole proprietor or Owner).
One of Baba's special features was that he always kept a sacred fire (Dhuni) burning. The ash from this fire was called Udi and it was freely distributed to the devotees at the time of their departure from Shirdi. What did Baba teach or hint by this Udi? Baba taught by His Udi that all the visible phenomena in the universe are as transient as the ash. Our bodies composed of wood or matter of the five elements, will fall down, after all their enjoyments are over, and be reduced to ashes. In order to remind the devotees of the fact that their bodies will be reduced to ashes, Baba distributed Udi to them. Baba also taught by the Udi that the Brahman is the only Reality and the universe is ephemeral and that no one in this world, be he a son, father or wife, is really ours. We come here (in this world) alone and we have to go out alone. It was found out and is even now found out, that the Udi cured many physical and mental maladies, but Baba wanted to din into the devotee's ears the principles of discrimination between the Unreal and the Real.
