*
The Way that can be told of is not an eternal way;
The names that can be named are not eternal names.
It was from the Nameless that Heaven and Earth sprang;
The named is but the mother that rears the ten thousand creatures, each after its kind.

Hence always rid yourself of desires in order to observe its secrets;
But allow yourself to have desires in order to observe its manifestations.
These two are the same
But diverge in name as they issue forth.
Being the same they are called mysteries,
Mystery upon mystery -
The gateway of the manifold Secretes Essence.
*

The Valley Spirit never dies
It is named the Mysterious Female.
And the gateway of the Mysterious Female
It is called the root of Heaven and Earth.
Dimly visible, it is there within us all the while;
Draw upon it as you will, yet use will never drain it.

Laozi (B.C. 600) - Dao De Jing - an excerpt

*In our acquisition of knowledge of the Universe (whether mathematical or otherwise) that which renovates the quest is nothing more nor less than complete innocence. It is in this state of complete innocence that we receive everything from the moment of our birth. Although so often the object of our contempt and of our private fears, it is always in us. It alone can unite humility with boldness so as to allow us to penetrate to the heart of things, or allow things to enter us and taken possession of us.
*

*This unique power is in no way a privilege given to "exceptional talents" --- persons of incredible brain power (for example), who are better able to manipulate, with dexterity and ease, an enormous mass of data, ideas and specialized skills. Such gifts are undeniably valuable, and certainly worthy of envy from those who (like myself) were not so "endowed at birth, far beyond the ordinary."
*

*Yet it is not these gifts, nor the most determined ambition combined with irresistible will-power, that enables one to surmount the "invisible yet formidable boundaries" that encircle our universe. Only innocence can surmount them, which mere knowledge doesn't even take into account, in those moments when we find ourselves able to listen to things, totally and intensely absorbed in child's play.
*

Alexander Grothendieck (A.D. 1928)

The true value of a human being can be found in the degree to which one has attained liberation from the self.
