Sai Baba of Shirdi (died 15 October 1918), also known as Shirdi Sai Baba, was an Indian spiritual master who is regarded by his devotees to be a manifestation of Sri Dattaguru and identified as a saint and a fakir. He was revered by both his Hindu and Muslim devotees during, as well as after his lifetime. According to accounts from his life, he preached the importance of "realization of the self" and criticized "love towards perishable things". His teachings concentrate on a moral code of love, forgiveness, helping others, charity, contentment, inner peace and devotion to the God and guru. He stressed the importance of surrender to the true Satguru, who, having trod the path to divine consciousness, will lead the disciple through the jungle of spiritual training.

Sai Baba also condemned distinction based on religion or caste. It remains unclear if he was a Muslim or a Hindu. This, however, was of no consequence to Sai Baba.His teachings combined elements of Hinduism and Islam: he gave the Hindu name Dwarakamayi to the mosque in which he lived,practised both Hindu and Muslim rituals, taught using words and figures that drew from both traditions and took samadhi in Shirdi. One of his well-known epigrams, Allah Malik (God is King) and Sabka Malik Ek (Everyone's Master is One), is associated with both Hinduism and Islam. He is also known to have said "Look to me, and I shall look to you" and Allah tera bhala karega.He was said to be an incarnation of Dattatreya. During Chaturmasya, when Gopal Deshmukh was in the gardens, a group of men jealous of his growing closeness to Sai Baba, hurled a brick at him. Gopal Deshmukh with his powers, kept the brick suspended in mid air. Yet another hooligan hurled another brick which hit Gopal Deshmukh. Young Baba pleaded with him to let him go away, as it was his own presence that was the cause of this trauma. Yet Gopal Deshmukh refused, medicated his injury with a shred of his own cloth and announced to Baba that the time for transfer for spiritual power to be transferred to Young Baba.

To this end, he asked for some milk to be got from a barren black cow nearby. On passing his hand over the cow from horn to tail, the cow yielded a lot of milk. This milk was given to the young Baba with blessings that the full power of the Guru should be transferred to the shishya. This was the only Diksha Baba is known to have had. As for Sakthi Nipata (transfer of power), the chieftain who hurled the injury-inflicting-brick on Gopal Rao Deshmukh, fell dead immediately. His accomplices pleaded with Gopal Deshmukh for forgiveness, who said that it is Young Baba who now has all the powers and he himself is powerless. Baba took some of the dust from his Guru's feet and placed it on the corpse which came back to life. In later life, Baba admitted that he did have the power to bring back people from the dead.  Source : Wikipedia
