Chapter 2, Part 2C - Lieh Tzu

'At the end of nine years my mind gave free rein to its reflections, my mouth free passage to its speech. Of right and wrong, profit and loss, I had no knowledge, either as touching myself or others. I knew neither that the Master was my instructor, nor that the other man was my friend. Internal and External were blended into Unity. After that, there was no distinction between eye and ear, ear and nose, nose and mouth: all were the same.

'My mind was frozen, my body in dissolution, my flesh and bones all melted together. I was wholly unconscious of what my body was resting on, or what was under my feet. I was borne this way and that on the wind, like dry chaff or leaves falling from a tree. In fact, I knew not whether the wind was riding on me or I on the wind.

'Now, you have not spent one whole season in your teacher's house, and yet you have lost patience two or three times already. Why, at this rate, the atmosphere will never support an atom of your body, and even the earth will be unequal to the weight of one of your limbs!

'The only way to etherealize the body being to purge the mind of its passions.

'How can you expect to walk in the void or to be charioted on the wind?'

Hearing this, Yin Sheng was deeply ashamed. He could hardly trust himself to breathe, and it was long ere he ventured to utter another word.
