The following story – originally told in a Upanishad (collection of philosophical texts which underline the Hindu religion) – is about ten men who went on an arduous pilgrimage to a faraway holy city. At one point on their journey they had to carefully make their way across a roaring river, which was surrounded by jagged rocks. When they finally reached the other side of the river, the leader of the group decided to count everyone to make sure they had all crossed safely, and so he lined each of the pilgrims up and started to count.
When the leader counted the last head, he discovered with horror that only nine men had made it across. He then asked each of the pilgrims to count. Sure enough each one only counted nine. A wise stranger came upon the scene and discreetly asked what had happened to elicit such an outpouring of grief. “We are pilgrims,” said the leader. “There were ten of us when we began our journey, but now one of our brothers has been lost in the river.” The stranger quickly noticed that by his count there were ten pilgrims. He asked: “Sir, would you please count everyone again just to make sure?”
“Yes,” replied the leader who began counting aloud, “one, two, three… eight, and nine! Oh alas, one is gone!”
“But sir,” said the stranger, “you have forgotten to count yourself!” And so, the tenth man was found.
