Once upon a time, the Taoist Master Chuang Tzu dreamed he was a butterfly flying joyfully everywhere. In his dream, he had no conscious awareness of his individuality as a separate entity with the entire Universe. He really was a butterfly. Suddenly, he woke up and found himself lying alone as a person again. He thought with himself;
“Was I a man that dreamed to be a butterfly before, or am I a butterfly that is dreaming to be a man?”
Another story tells us that Master Takuan was on his death bed. A very devoted disciple came to the beloved master and asked:
“Master, what would be your legacy to this world?
Takuan answered him that he did not have any legacy in the world.
But the Disciple insisted again asking: “Master don’t you have anything to say?”
After long moments, the Master finally answers:
“Life is nothing more than just a dream”
In saying this, The Master expired.
