"He perceives the oneness of everything, does not know about duality in it". Tchuang Tzu

"The True Man In dwelling he has no shape, and in abiding he has no place. In movement he has no form, and in quiescence he has no body. He is there but looks as if he were gone, he is alive but looks as if he were dead. He comes in and out of the spaceless and has gods and demons at his orders; he sinks into the unfathomable and enters into the spaceless. He exchanges his form with what is different from him. End and beginning for him are like a ring, and nobody knows his patterns. This is how his essence and spirit can lead him to ascend to the Dao. This is where the True Man roams. As for inspiring and expiring while emitting the sounds chui and xu, exhaling the old and inhaling the new [breath], hanging like a bear and stretching like a bird, bathing like a duck and leaping like a gibbon, glaring like an owl and staring like a tiger--these are for the people who 'nourish their form', and he does not confuse his mind with them."
Huainan zi

"Desirous of lust and beautiful sight, one injures one’s essence and loses one’s vision."Ho Shang Gong

"Therefore the sage embraces the OneAnd becomes the model of the world."

"Can you keep the spirit and embrace the One without departing from them?"

Lao Tzu

"The ten thousand things have ten thousand different forms but in the final analysis they are one. How did they become one? Because of non-being…. Therefore in the production of the myriad things, I know its master. Although things exist in ten thousand different forms, their material forces are blended as one."Wang Bi
