The Self (Soul) is an Omnipresent (present everywhere) & Omniscient (all-knowing) reality. Sri Ramana demonstrated this very truth to his disciples by revealing the details of a beach he had never visited.
A couple from Peru, who had heard of Sri Ramana Maharshi’s greatness, came to the Ashram. Being poor they had to save enough money for a few years to become deck passengers (on a ship). To the couple, the Maharshi’s presence on earth seemed the second coming of the Christ himself and they longed to see him.
One evening when they sat before Ramana Maharshi, the talk turned to Peru. The couple was describing the seacoast and beach of their town.
Just then Maharshi remarked, “Is not the beach paved with marble slabs, with coconut palms planted in between? Are there not marble benches in rows facing the sea, and did you not often sit on the fifth of those with your wife?” This remark came as a great astonishment to the couple and they were at a loss to understand as to how the Maharshi could know such minute details.
Ramana Maharshi smiled and remarked, “It does not matter how I can tell. Enough if you know that the Self is not limited by space and time.”
As noted in the book: Face to Face with Sri Ramana Maharshi (Incident #115)
