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 described is not the eternal Tao. The name that can be spoken is not the eternal Name. The nameless is the boundary of Heaven and Earth. The named is the mother of creation. Freed from desire, you can see the hidden mystery. By having desire, you can only see what is visibly real. Yet mystery and reality emerge from the same source. This source is called darkness. Darkness born from darkness. The beginning of all understanding.
There is a reality outside the world, that is to say, outside space and time, outside man's mental universe, outside any sphere whatsoever that is accessible to human faculties. Corresponding to this reality, at the centre of the human heart, is the longing for an absolute good, a longing which is always there and is never appeased by any object in this world. Another terrestrial manifestation of this reality lies in the absurd and insoluble contradictions which are always the terminus of human thought when it moves exclusively in this world. Just as the reality of this world is the sole foundation of facts, so that other reality is the sole foundation of good. That reality is the unique source of all the good that can exist in this world: that is to say, all beauty, all truth, all justice, all legitimacy, all order, and all human behaviour that is mindful of obligations. Those minds whose attention and love are turned towards that reality are the sole intermediary through which good can descend from there and come among men. Although it is beyond the reach of any human faculties, man has the power of turning his attention and love towards it. Nothing can ever justify the assumption that any man, whoever he may be, has been deprived of this power. It is a power which is only real in this world in so far as it is exercised. The sole condition for exercising it is consent. This act of consent may be expressed, or it may not be, even tacitly; it may not be clearly conscious, although it has really taken place in the soul. Very often it is verbally expressed although it has not in fact taken place. But whether expressed or not, the one condition suffices: that it shall in fact have taken place. To anyone who does actually consent to directing his attention and love beyond the world, towards the reality that exists outside the reach of all human faculties, it is given to succeed in doing so. In that case, sooner or later, there descends upon him a part of the good, which shines through him upon all that surrounds him.
