Sai Baba of Shirdi (1838 – 15 October 1918; Resided in Shirdi), also known as Shirdi Sai Baba, was a spiritual master who was and is regarded by his devotees as a saint, fakir, avatar (an incarnation of God), or sadguru, according to their individual proclivities and beliefs. He was revered by both his Muslim and Hindu devotees, and during, as well as after, his life on earth it remained uncertain if he was a Muslim or Hindu himself.
I had a Guru. He was a great saint and most merciful. I served him long – very, very long; still, he would not blow any mantra in my ears. I had a keen desire never to leave him but to stay with him and serve him and at all cost receive some instruction from him.
