Clear! as though right by your side.
Vague! as though it will not be attained.
Indescribable! as though beyond the limitless.
The test of this is not far off:
Daily we make use of its inner power.
The Way is what infuses the body,
Yet people are unable to fix it in place.
It goes forth but does not return,
It comes back but does not stay.
Silent! none can hear its sound.
Suddenly stopping! it abides within the mind.
Obscure! we do not see its form.
Surging forth! it arises with us.
We do not see its form,
We do not hear its sound,
Yet we can perceive an order to its accomplishments.
We call it "the Way."
