From Tao Te Ching (The Tao).tao

Before the universe is born
something formless and perfect exists.

Serene. Empty.
Solitary. Unchanging.
Infinite. Eternally present.

It is the Mother of the universe.

For lack of a better name,
I call it the Tao.
I call it great.
Great meaning boundless.

Boundless is eternally flowing;
ever flowing, it is constantly returning.

And so the Way is great,
heaven is great,
earth is great,

are great.

Thus: to know humanity,
understand earth.

To know earth,
understand heaven.

To know heaven,
understand the Way.

To know the Way,

the great Mother

Note 1: This is my interpretation of the 25th, central, teaching of the Tao Te Ching, relying on the wonderful scholarship of Jonathan Starr’s The Definitive Edition. (Shame about the title; there’s no such thing as the ‘definitive’ edition of anything — and most certainly not of writing as distant in time and place, and as deliberately ambiguous, as the verses of The Tao.)
Note 2: Yes manly boys, this one
is for you too.
