Om Sai Shri Sai Jaya Jaya Sai

On this day, two other important events took place.  (1) Mr. Dadasaheb Khaparde was given permission to return home, and (2) the night Arti in Chavadi was commenced.  The Wada was complete and was inhabited on the Rama-Navami day in 1911 A.D., with due rites and formalities, (3) Then another Wada or palatial mansion was put up by the famous building, but all the amount was well utilized, as Sai Baba's body is resting in this Wada, which is now called the Samadhi Mandir.

Bow to Shri Sai - Peace be to all
