Shri.Dinkar Rao Jaiker is the Son of Sai mahabhakta Shri.Shyam Rao Jaiker. He was a resident of Vile Parle, Mumbai. He was fortunate to see Sai Baba and be with Him.
Once, when he was in the Dwarakamai Masjid with Him, there was a severe storm howling. The wind and rain were fierce. After a few minutes, Sai Baba stepped on the edge of the premises and cried out "Jara Thava" meaning "Stop a Bit" in Marathi obviously to the storm and very quickly the storm abated. This incident clearly showed that Sai Baba possessed "Ashta Siddhi's" had thus had total control over nature.
