The Tao has its reality and its signs but is without action or form.
You can hand it down but you cannot receive it; you can get it but
you cannot see it. It is its own source, its own root. Before heaven
and earth existed it was there, firm from ancient times. It gave
spirituality to the spirits and to God; it gave birth to heaven and to
earth. It exists beyond the highest point, and yet you cannot call it lofty;
it exists beneath the limit of the six directions, and yet you cannot call it
deep. It was born before heaven and earth, and yet you cannot say it
has been there for long; it is earlier than the earliest time, and yet you
cannot call it old.

~Chuang Tzu 6
