Once I dreamed I was a butterfly, and now I no longer know whether I am Chuang Tzu, who dreamed I was a butterfly, or whether I am a butterfly dreaming that I am Chuang Tzu.
ZhuangziWhen you're dreaming, you don't know it's a dream. You might even interpret a dream in your dream - and then wake up and realize it was all a dream. Perhaps a great awakening will reveal this to be a dream as well.
ZhuangziThe birth of a man is the birth of his sorrow. The longer he lives, the more stupid he becomes, because his anxiety to avoid unavoidable death becomes more and more acute. What bitterness! He lives for what is always out of reach! His thirst for survival in the future makes him incapable of living in the present.
