Directions: Read the paragraph and answer the question that follows. The greatest hunger in life is not for food, money, success, status, security, or even love from the opposite sex. The deepest hunger in life is a secret that is revealed only when a person is willing to unlock a hidden part of the self. In the ancient traditions of wisdom, this quest has been likened to diving for the most precious pearl in existence, a poetic way of saying that you have to swim far out beyond shallow waters, plunge deep into yourself, and search patiently until the pearl beyond price is found. The pearl is also called essence, the water of life, holy nectar - labels for what we, in our more prosaic scientific age, would simply call transformation. Transformation means radical change of form, the way a caterpillar transforms into a butterfly. In human terms, it means turning fear, aggression, doubt, insecurity, hatred, and emptiness into their opposites. It comes down to the age old choice of separation or unity.
