Thus, sentient beings are the Buddha. The Buddha is one with them. Both consist entirely of the one "substance." The phenomenal universe and Nirvana, activity, and motionless placidity - all are of the one "substance."
We join spokes together in a wheel,
We shape clay into a pot,
We hammer wood for a house,
We work with being,
but it is the center hole
that makes the wagon move.
but it is the emptiness inside
that holds whatever we want.
but it is the inner space
that makes it livable.
but non-being is what we use.
The one Mind, like a mirror, reflects everything brightly, and knows no limitations;
It pervades the entire universe in even its minutest crevices.
These worlds and all its contents, multitudinous in form, are reflected in the one Mind,
Which, shining like a perfect gem, has no 'outer' or 'inner'.
