Tao is beyond words and beyond understanding. Words may be used to speak of it, but they cannot contain it. Tao existed before words and names, before heaven and earth, before the ten thousand things. It is the unlimited father and mother of all limited things. Therefore, to see beyond boundaries to the subtle heart of things, dispense with names, with concepts, with expectations and ambitions and differences. Tao and its many manifestations arise from the same source: subtle wonder within mysterious darkness. This is the beginning of all understanding.
The wise person dines on something more subtle: He eats the understanding that the named was born from the unnamed, that all being flows from non-being, that the describable world emanates from an indescribable source.
Clay is moulded to make a vessel, but the utility of the vessel lies in the space where there is nothing. . . . Thus, taking advantage of what is, we recognize the utility of what is not.
Eliminate mental muddiness and obscurity; keep your mind crystal clear. Allow your pure original insight to emerge. Quiet your emotions and abide in serenity. Don't go crazy with the worship of idols, images, and ideas; this is like putting a new head on top of the head you already have. Remember: if you can cease all restless activity, your integral nature will appear.
