The widower & his lost son.

Once upon a time there was a widower living with his 4 year old son. He was quite attached with his son. One day while he was away for the business purpose, the looters came & burnt the whole village & took his son away. When the widower returned back, he was so shocked & terrified to know what had happened while he was away. He cried a lot & took the burnt corpse of a little boy to be his son & cried uncontrollably. He then organised a cremation ceremony, gathered the ashes and put them in a nice bag which he always kept with him in the memory of his son. After sometime his son managed to run away from the looters & went back to his father's new cottage at the midnight and knocked the door. The father, still in trauma asked:"Who are you?" The boy answered, it's me dad, open the door! but in his troubled state of mind he was convinced that his son was dead, the father thought that some other boy was playing a prank on him. He scolded: "Go away" and continued to cry. After sometime, his son left the place and from that night the father and son never saw each other.

After this story, the Buddha said: "Sometime, somewhere, you take something to be the truth. If you cling to it so much, even when the truth comes in person and knocks on your door, you will not open it."
