Once, a young man was traveling with his teacher to a place far enough away. The journey takes days. Since they are just walking, they should rest if they are tired or look for a place to stay if it is late in the evening.One day, on the way, they stopped to rest and unwind. They were in a forest. The teacher asks his students to seek drinking water.The young man then left. After searching to and fro, he finally managed to find a river whose water is clear enough. So he went to the river to take drinking water.But unfortunately, there are some women who were washing clothes in the river. Of course the river water becomes dirty and can not drink. In his heart he said, "The water is so dirty. How can I give this water to the teacher? "The young man rushed back to meet his teacher.The young man said, "Master, actually I've found the river. Unfortunately, the water can not be taken. Someone washes there so the water gets dirty. "The teacher told him, "Oh, I see. Just wait a minute and then go back there. "Without asking, the young man obeyed his famous wise teacher's command. After a while, he returned to the river. Upon arrival, he did not see the women who had been finished washing. There was only a bunch of kids in the shower. Seeing this, he immediately returned to see his teacher.He said, "Master. I was back in that river. But, the children are bathing. Surely the water can not be taken to drink. How good is that? Do we just go on and look for water elsewhere? "The teacher smiled and replied, "Oh, that's so. Just wait a minute and then go back there. "The young man was confused and wondered why his teacher kept asking him to go to the river when it was clear he would not be able to get water to drink.But he also obeyed what his teacher said and after a while, he returned to the river.Arriving there, it turns out there is no one in the river. The children have finished bathing. He approached to the riverbank and saw that the water had become clear. With a smile, he drank the water and then put water into the drink.The young man immediately returned and told his teacher. He said, "Master, it turns out after I returned to the river, the water was clear. So we can get some water. "With a smile his teacher asked, "The water becomes clear because the river water is always flowing. The water may be dirty, but it's only temporary. After a while the water will come back clear as the water keeps flowing. Dirty water flowed away and replaced with clear water. All this happens by itself. "The teacher went on, "So do you. You can learn from this flowing water. Whenever you are troubled by a lot of complicated minds full of problems, just let it flow. Be patient and give time, then the mind will disappear and be replaced with a clearer mind. It will happen by itself. "The young man said, "Thank you teacher for giving me a very valuable lesson."
