Here is an excerpt from a letter written to me by Sri C. R. Parthasarathy, the author of the book "Back to Reality".  Sri Parthasarathy had numerous visions of the Sathya Sai form and Divine Revelations through those visions.

Om Sri Sai Ram

Dear Sri Narayan,

Sai Ram,

Sorry for the delay in contacting your good self. For everything and to everybody, Baba’s blessings carry.

[...]  

During the month of February I experienced His  (Sri Sathya Sai Baba's) presence in Trayee Brindavan, Bangalore, at night from 2:15 AM up to 3:00 AM. It is true that He travels and visits few places, where He was presenting Himself in His previous body. This is not a vision, but I personally was on the spot when we were there on service duty. Lights were on in Swami’s personal room, even though the entire building was locked.

[...]

Mr. Narayan, now I narrate a very interesting vision that I had a few months back.

Place is Puttaparthi. The hills on the eastern and southern sides of the town were filled with erected small tents. The colour of the tents was pink with yellow. There, small tents were fitted with flags that were fluttering. Color of the flags was green with a  shape.

After this, I saw water jumping above from a bore well of 8 inches, that was dug in between the Ganapathi temple and the Subramanian temple (near the main gate), to a height of about 10 feet. This was done by Swami. Water was flowing towards Chitravathi river and the holy river converted into a small lake. This was to meet the water demand of the people, since several lakhs of people (not devotees) would gather and stay there to see Bhagawan for a reason not known so easily.

In a fraction of a few seconds, I heard His vibrant speech, and it ended within a few seconds. The sound was vibrant, just as He used to deliver at His fifty years of age. 

This is an indication to support the belief and to confirm that somewhere during the month of November 2015 or so, He will physically appear on the dais of the Sai Kulwant Hall to make it true to the world that He has returned.

But Mr. Narayan, who are we to fix the exact date and year to that Divine power of Baba? It is His Leela and Divine games.

Who are those people in those tents and why they had gathered there? They were several lakhs in number. Swami alone knows for what purpose they thronged to meet Swami. Now I can feel that He is in close proximity to promote His purpose and that may happen anytime in a time bound manner. People around the world will truly come to know that Bhagawan Baba reappeared in the same form and for what purpose. Let us pray to witness that Golden era!

Yours very affectionately

C. R. Parthasarathy

Jay Sai Ram!
