There was a monk who one day found himself in the presence
of the King, who was not a very kind person.
During their conversation, for no apparent reason, the King
said to the monk, "you know, you look just like a pig."
To this the monk calmly replied, "and you, Your Majesty,
look just like an angel."
A bit bewildered, the King demanded, "how could you tell me
I look like an angel when I just said you look like a pig?"
The monk responded, "when a pig looks, it sees pigs. When an
angel looks, it sees angels."
