As is in Shri Sai Satcharita, by Hemadpant .. Chapter XXIII Page 120

Om Sai Shri Sai Jaya Jaya Sai

We regard Sai Baba as an Incarnation of God, for reasons already stated, 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 (Varnas) in this life.

Bow to Shri Sai - Peace be to all
