Once upon a time, I, Chuang Chou, dreamt I was a butterfly, fluttering hither and thither, to all intents and purposes a butterfly. I was conscious only of my happiness as a butterfly, unaware that I was Chou. Soon I awaked, and there I was, veritably myself again. Now I do not know whether I was then a man dreaming I was a butterfly, or whether I am now a butterfly, dreaming I am a man. Between a man and a butterfly there is necessarily a distinction. The transition is called the transformation of material things.
Just remembered this quote sort of so thought I should look it up to see who actually said it. It had been a favourite of mine for some time. I like how some themes keep recurring, butterfly and umbrellas, wings transitions/metamorphosis have always had held a special place in my thoughts.
Not entirely sure why I put this in but it seems important.
