Saburo Hasegawa The Butterfly Dream — from Chuang Tzu, 1956

Once upon a time, I, Chuang Tzu, dreamed I was a butterfly flying happily here and there, enjoying life without knowing who I was. Suddenly I woke up and I was indeed Chuang Tzu. Did Chuang Tzu dream he was a butterfly, or did the butterfly dream he was Chuang Tzu? There must be some distinction between Chuang Tzu and the butterfly. This is a case of transformation.
