POSSIBILITY ENTIRE

Ever without desires (/attachment) then perceive its essence (/your true nature)
Ever with desires (/attachment) then perceive its manifestation (/your individual form)

Identifying with [the mind’s] pure awareness reveals its true nature
Identifying with [the mind’s] limited awareness reveals the world of thoughts

The state of wu yü reveals, “I am the Essence”
The state of yu yü reveals, “I am the body”

The Eternal, [seen] through one’s pure awareness, reveals its essence
The Eternal, [seen] through one’s ego-concepts, reveals its outer forms

The Eternal appears in its true wonder to one whose mind is perfectly still
The Eternal appears ordinary, as the apparent forms of this world, to one whose mind is dictated by its thoughts

By constant Non-being, we desire to perceive its essence
By constant Being, we desire to perceive its manifestation

Therefore let there always be non-being, so we may see their subtlety, and let there always be being, so we may see their outcomes. (Chan)

In eternal non-existence, therefore, man seeks to pierce the primordial mystery; and, in eternal existence, to behold the issues of the Universe. (Chalmers)

The thought-free awareness, brought about by the mind turned within, lets a person behold his true nature — eternal, wondrous, the manifestation of one reality.
The awareness that results from the mind turned outward lets a person see his life in this world — passing, ordinary, filled with differences.

A mind that is perfectly still and turned inward reflects the pure awareness of its boundless nature;
A mind that is restless and turned outward lives in the cage of its own thoughts.
