Three monks were meditating together by the riverside. Two of them were senior and considered themselves to be more advanced than the third monk, who actually had remained doubtful of their claim. Their monastery was on the other side of the river. “It’s normal to have supernatural powers when you are enlightened" one of them said. He got up walked on water, across the river, and came back walking on the water. “I’d just gone to bring my shawl" The second monk showed no reaction but the junior one sat agape. Before he could get over the miracle, he had just witnessed, the second senior monk also got up and performed the same feat. “I’d forgotten my bowl back there,” he said in a matter of fact tone while sitting down. Now, the junior monk was almost shell-shocked. He realized it was their confidence and conviction that they could walk on water. Not to be outdone, and to test his powers, he too got up with the intention to walk on water. Two steps from the bank and he fell down in the river, his robe soaked in water. The senior monks laughed hysterically. Still not giving up, he came out and tried to run across the river. He fell down again. “Do you think we should tell him,” the first monk said to the other, “where the stones are?” Building your concentration, the most important aspect of a good life, is like walking on water. But once you know where the stones are, it becomes a lot easier to do so. Concentration is focus with precision–one careful step at a time, one moment at a time. The only way to retain your concentration is by retaining it in this moment, the present moment, and then the next moment, and the next, and the next and so on. If you maintain the sharpness of your concentration from one moment to the next, you stand to gain extraordinary rewards from your life.
