Short story great ideal

Two guys were very best friends. One day an argument erupted between them . Mr X said some very hash words to Mr Y. Mr Y was very hurt by these words and he left without a word. Mr X felt very guilty later and did not to how to face Mr Y again. As he walked thinking he saw a Sage meditating under a tree. He went to the sage and told him what happened and asked for a solution. The sage thought for a while and told Mr X " Take a bag of cotton and go to the top of the mountain and let it fly. Then gather them all back and bring them to me then I will give you the solution." . Mr X thought it was a simple task and let all the cotton to fly from the top of the mountain. But he could not gather them back as it had flown away. After several futile attempts, he went back to the sage and said that he could not gather them back how much ever he tried. The sage smiled and replied
" WORDS THAT WE UTTER ARE ALSO LIKE THE COTTON WHICH YOU COULD NOT GATHER. ONCE SAID YOU CAN NEVER TAKE THEM BACK"

So think hard before saying anything hurtful to others.
