' Chuang Tzu dreamed that he was a butterfly.

All day long, he floated on the breeze Without a thought of who he was or where he was going. When he awoke, Chuang Tzu became confused.

'Am I a Man”, he thought, 'who dreamed that I was a butterfly? Or am I butterfly, dreaming that I am a man?

Perhaps my whole waking life is but a moment in a butterfly's dream!'
