Once lord Buddha was walking from one village to another with a few of his disciples. While they were traveling, they reached the bank of the river. Lord Buddha stopped them and told one of his disciples."I'm thirsty' get me some water from that lake to drink." The disciple boy walked up to the lake. When he reached there, he noticed that some people were washing clothes in the water and, at that right moment, a bull started crossing the lake from this edge of ghat to the other edge of lake. Consequently the water become very muddy. Then the disciple boy thought, "How can I give this muddy water to Buddha?" As It is not suitable for drinking. So he came back and told the Buddha, "The water is very muddy there and I don't think it's fit to drink". So the lord Buddha said all right, let us take a little rest here. After half an hour, again he asked the same disciple boy to go back to the lake and get him some water to drink. The disciple boy obediently went back to the lake. This time he found that the lake had absolutely clear water. The mud had settled down and the water above it look fit to be had. So he collected some water in a pot and brought it to the lord Buddha. Lord Buddha looked at the water, and he looked up at the disciple boy and said, see, you let the water be and the mudd settled down on its own. It didn't require any effort, and you got clear water. MORAL---Our mind is like that as well. The more you try to forget the longer you'll remember. So when you feel disturb just let it be. Give a little time and think deeply. You don't have to put in any effort to calm it down. We can judge, and take best decisions in our life when we stay calm.
