Once, there was a very wealthy man who was suffering from severe eye pain. He consulted many physicians and was being treated by several. He consumed lots of drugs and underwent hundreds of injections. But the ache persisted and, in fact, was getting worse.
At last, a monk who was supposed to be an expert in treating such patients was called for by the suffering man. The monk understood his problem and said that he should concentrate only on the color green for a month. He should not let his eyes fall on any other colors. It was a strange prescription, but he was desperate and decided to try it.
The millionaire gathered a group of painters and purchased barrels of green paint. He directed that every object his eye was likely to see should be painted green, just as the monk had directed. When the monk came to visit him after a few days, following their orders, the man’s servants ran with buckets of green paint and poured it on the monk, who was dressed in his red robes.,
The monk just laughed and said, "If only you had purchased a pair of green-tinted eyeglasses worth just a few dollars, you could have saved these walls and trees and pots and everything around you, as well as a large share of your fortune.
Moral of the story: You cannot paint the world green. Change YOUR vision, and the world will appear accordingly.
