Let us change our vision!
There was a millionaire who was bothered by severe eye pain. He consulted quite a number of physicians for his problem but could not be cured. finally he consulted a monk who was considered an expert in treating such patients. The monk understood his problem and advised him that for a few days he should concentrate only on green colours.
The millionaire got together a group of painters and purchased barrels of green color and directed that every object his eye was likely to fall be painted in green colour just as the monk had directed.
When the monk came to visit him after few days, the millionaire's servants ran with buckets of green paints to pour on him as he was wearing a red dress. Seeing this the monk laughed and said "If only you had purchased a pair of green spectacles, costing just a few rupees, you could have saved these walls and trees and pots and all other articles thereby saving a large fortune. You cannot paint the world green."
Let us change our vision and the world will appear accordingly. It is foolish to change the world, let us change ourselves first.
