Mysticism in Taoism

[John Zeger]

The mystical message that Spirit is the essence of everything is
clearly evident in the ancient Taoist scripture, the Tao Te Ching,
attributed to the sage Lao Tsu. The Tao (translated as the Way) is
beyond form and although ineffable it can be intuited.

In Chapter Six of the Tao Te Ching it is written:

The Tao is the breath that never dies.
It is a Mother to All Creation.
It is the root and ground of every soul
-- the fountain of Heaven and Earth, laid open.
Endless source, endless river
River of no shape, river of no water
Drifting invisibly from place to place
... it never ends and it never fails.

Again, in Chapter Twenty-one:

The Body of The Tao is a mist beyond your eyes
Tao of No Body, and yet within it is All Creation.
Like a seed in the dark, and a dim light
And from it, comes everything.
Root, stem, leaf ... its essence is in everything.
Everything is born from this Tao
I say so, and I can prove it!
From the beginning of time until now
the Tao is eternal because it is Creation.
How do I know the Tao is the root of all being?
Because I know this.

(Tao Te Ching, translated by Man-Ho Kwok, Martin Palmer and Jay Ramsay)
