I received this story on some group a couple of weeks back. I do not know the source now. It is so wonderful that I could not stop putting it here.
A young widower lived with his five-year-old son. He cherished his son more than his own life. One day he left his son at home while he went out on business. When he was gone, brigands came and robbed and burned the entire village. They kidnapped his son. When the man returned home, he found the charred corpse of a young child lying beside his burned house.
He took it to be the body of his own son. He wailed in grief and cremated what was left of the corpse. Because he loved his son so dearly, he put the ashes in a bag which he carried with him everywhere he went. Several months later, his son managed to escape from the brigands and make his way home. He arrived in the middle of the night and knocked at the door. At that moment, the father was hugging the bag of ashes and weeping. He refused to open the door even when the child called out that he was the man’s son. He believed that his own son was dead and that the child knocking at the door was some neighborhood child mocking his grief. Finally, his son had no choice but to wander off on his own. Thus father and son lost each other forever.
If we are attached to some belief and hold it to be the absolute truth, we may one day find ourselves in a similar situation as the young widower. Thinking that we already possess the truth, we will be unable to open our minds to receive the truth, even if truth comes knocking at our door.
