Sai Baba of Shirdi (1838 – 15 October 1918; resided in Shirdi), also known as Shirdi Sai Baba, was an Indian spiritual master who was and is regarded by his devotees as a saint, fakir, and satguru, according to their individual proclivities and beliefs. He was revered by both his Hindu and Muslim devotees, and during, as well as after, his life it remained uncertain if he was a Hindu or a Muslim himself. This however was of no consequence to Sai Baba himself. Sai Baba stressed the importance of surrender to the guidance of the true Satguru or Murshid, who, having gone the path to divine consciousness himself, will lead the disciple through the jungle of spiritual training.
Sai Baba remains a very popular Master, especially in India, and is worshiped by people around the world. He had no love for perishable things and his sole concern was self-realization. He taught a moral code of love, forgiveness, helping others, charity, contentment, inner peace, and devotion to God and guru. He gave no distinction based on religion or caste. Sai Baba's teaching combined elements of Hinduism and Islam: he gave the Hindu name Dwarakamayi to the mosque he lived in, practised Muslim rituals, taught using words and figures that drew from both traditions, and was buried in Shirdi. One of his well known epigrams, "Sabka Malik Ek" ("One God governs all"), is associated with Hinduism, Islam and Sufism. He also said, "Trust in me and your prayer shall be answered". He always uttered "Allah Malik" ("God is King").
