During Saibaba's presence nobody knew the parents, birth or birthplace and birth time of Shri Shirdi Sai Baba. So many Baba's ardnet devotees asked questions to Baba but but no one had convincing answer or definite information has yet been obtained. Practically no one knows about these matters.
He first manifested Himself as a young lad of sixteen under a Neem tree in Shirdi for the sake of Bhaktas. Even then He seemed to be full with the knowledge of a Brahman (the only one Universal force or energy governing all matters). He had no desire for worldly objects and pleasures even in dream. He renounced Maya (delusion) and Mukti (deliverance) was at His feet. With His blessings many souls attained liberation by HIS mystic plays and without any 'formal' teaching or philosophical discussion. For all the seekersHE uttered only three words- 'ALLAH ACHCHA KAREGA' by way of HIS blessings. Everything will be fine by the GRACE OF GOD.
When the marriage - party came to Shirdi, it alighted at the foot of a Banyan tree in Bhagata Mhalsapati’s field near Khandoba’s temple. The carts were loosened in the open courtyard of Khandoba’s temple and the members of the party descended one by one, and the Fakir also got down. Bhagat Mhalsapati saw the young Fakir getting down and spontaneously accosted Him "YA SAI" (Welcome Sai). Others also addressed Him as Sai and thenceforth he became known as Sai Baba.
Upon His return to Shirdi, Baba stayed there for an unbroken period of sixty years, after which He took His Maha-Samadhi in the year 1918.
Initially, Sai Baba stayed on the outskirts of the village of Shirdi, then under a neem tree for four to five years at the spot now called Gurusthan, before shifting to an abandoned mosque which later became known as Dwarkamai.
Slowly His greatness was revealed and His fame spread far and wide, until by the end of His life He was attracting thousands of people to Shirdi. In the last decade of His life, Baba was worshipped with all pomp and ceremony and the mosque was likened to a maharajah’s ‘darbar’, yet Baba never changed His simple and austere lifestyle of the Puritans.
