《庄子·外篇·在宥》
毁掉你的形体，堵塞你的听觉、视觉，常规和万物一起被忘记，与自然之气相融通，解除你的心虑，释放你的精神，无所用心而内心混沌。
堕尔形体，吐尔聪明，伦与物忘，大同乎涬溟。解心释神，莫然无魂。
Destroy your form, block your hearing and vision, let conventions and all things be forgotten, merge with the qi of nature, release your mind, let your spirit be free, and let your heart be chaotic.
