The story of a selfish and greedy man

A saint gave one of his disciples a magic item which could fulfill all his desires. The only snag was that his neighbour would automatically get double the amount. That man got all that he wanted-money, elephants, horses, cows, buffaloes etc. but his neighbours got all that too, doubled. He was jealous of his neighbours on that account. He was always thinking of desiring something that would harm his neighbours. At long last, an idea struck him and he wished that he might lose one of his eyes. Then he got one arm and leg broken, and the neighbours lost both their arms and legs. He at this stage happened to have an attack of paralysis which completely immobilized him. Even his normal eye, the leg and the hand were rendered unless. He requested the magic article to restore his normalcy but this was rejected, because the neighbours had to get the double the amount and they couldn't possibly get four eyes, legs, arms etc. In desperation he asked for just one eye, leg and arm and this time his request was granted. And lo! The neighbours were also as hale and hearty as ever. He remained deformed for the whole of his life, while his neighbours enjoyed normal health. This is what happens if you wish others ill.

Note: Selfishness must be purged in practical life in order to obtain peace and bliss
