Listen, it cannot be heard - it is beyond sound.
Grasp, it cannot be held - it is intangible.
These three are indefinable;
Therefore they are joined in one.
From above it is not bright;
From below it is not dark:
An unbroken thread beyond description.
It returns to nothingness.
The form of the formless,
The image of the imageless,
It is called indefinable and beyond imagination.
Stand before it and there is no beginning.
Follow it and there is no end.
Stay with the ancient Tao,
Move with the present.
Knowing the ancient beginning is the essence of Tao.
You can't see Tao,
no matter how hard you look.
You can't hear Tao,
no matter how hard you listen.
You can't hold on to Tao,
no matter how hard you grab.
But it's there.
It's in you, and it's all around you.
