One day Buddha was travelling from one town to another town along with his followers. On the way, they took a rest and the Buddha asked one of his followers to get some water from the nearby lake.A disciple walked up to the lake and he noticed that some people were washing clothes in the lake water and also a bullock cart crossing through the lake.As a result, water became muddy and the disciple thought this muddy water cannot be given to Buddha to drink. He came back to Buddha and told that the water was muddy and not suitable for drinking.
After a while, Buddha again asked the same disciple to go back to the lake and get some water. The disciple also went to the lake and found that mud was settled down and the water was clean enough to drink.So he collected some water in a pot and brought it to Buddha.
Buddha looked at the water and looked up at the disciple and said “what did you do to make the water clean to drink? You just allowed it as such to settle down the mud. Similarly, when your mind is in a disturbed state, you cannot make use of it effectively for decision making or doing anything useful. Give a little time to settle it down, your mind becomes in a positive state and you can produce results “
