The distance between truth and falsehood

One day Akbar asked Birbal, "Can you tell me the distance between truth and falsehood? How far are they from one another?"

Birbal replied, "It is the distance between the eye and the ear. What we see with the eye is the truth, and what we hear with the ear is all gossip, all falsehood. So the distance between truth and falsehood is about three inches."
