“The Tao is hidden, and has no name; but it is the Tao which is skilful at imparting (to all things what they need) and making them complete.”

“The Tao that can be told is not the eternal Tao. The name that can be named is not the eternal name. The nameless is the beginning of heaven and earth. The named is the mother of ten thousand things. Ever desireless, one can see the mystery. Ever desiring, one can see the manifestations. These two spring from the same source but differ in name; this appears as darkness. Darkness within darkness. The gate to all mystery.”

“The Tao that can be told is not the eternal Tao.”

“When the highest type of men hear Tao,They diligently practice it.When the average type of men hear Tao,They half believe in it.When the lowest type of men hear Tao,They laugh heartily at it.Without the laugh, there is no Tao”

“This is what is called 'The mysterious Quality' (of the Tao).”

“el tao que puede ser expresado no es el verdadero tao.”
