It was on a cloudy June evening that Sathya Sai Baba was addressing an open air meeting at Mercara. The sky was overcast and gloomy rumblings of approaching rain could be heard, not far away. In fact, the rain poured on the hills on the horizon, stepped nearer and nearer, and came as far as Mahadevpet, half a mile away. Baba spoke quietly and calmly, holding the audience spell-bound, for over an hour and a half; at the end, He said, " Now, you can go home, for in about ten minutes you will get the rain that ought to have drenched you by now. "And, wonder of wonders, the rains came, as announced, ten minutes later, to the very second!

The Chitravathi River at Puttaparthi is subject to sudden floods, for it rises in the Nandi Hills and heavy rains in that region in Mysore State will bring down the waters many feet deep all along the miles. The Prasanthi Nilayam was built on an eminence away from the village to avoid these periodical floods which in some years invade the old Mandir, entering the prayer Shed, the kitchens and all the surrounding area. On many such occasions, Baba has stood on the edge of the water and said, "Ganga! It is enough, go back." and the waters have not risen more. Some years ago, during Navarathri, when the (Narayana Seva) feeding of the Poor was on, it rained all round the Nilayam, but not a drop fell in the precincts where people were being fed!
