God created Man 'happy'. But Man did not use happiness properly. So God took it back from him. God asked the Angels, "Where do we hide happiness?"
One of them said, "We should bury it deep in the earth."
God said "No... Man will dig deep into the earth and find it."
Another Angel said, "Well... in that case, we put it into the deepest sea."
But God said, "No... one day Man will go down into the depths of the sea. He can find it there easily."
All the Angels said together, "We cannot hide it in the earth, we cannot hide it in the sea... Then where can we hide it? What shall we do?"
God smiled and said, "I have a plan, we'll hide it in Man's heart. He will never think of looking for it there!!"
Man started his search for happiness from that day onwards. He never thought of looking for happiness in his own heart, and, the search is still on...
