Ramana Maharshi once told us the story of a man whom he had seen when he himself was a young man. This man was crippled, could not use his legs, and had to crawl. An old man suddenly appeared before him and commanded,"Get up and walk!" The cripple was so excited that he automatically rose up and found himself able to walk properly. When he looked round to see this strange benefactor, the man had vanished. The healing was permanent. The point here is first, not whether the vision was subjective or objective, but that the healer did not even have a familiar identity, was not recognized as a Christian saint or Hindu god, and second, that the sufferer was stimulated into having enough faith to obey the command to believe he was healed already; it was not a matter of time.
