Continuing posts on heschyia (or heschuia) here is a passage from “The Art of the Icon: A Theology of Beauty” by Paul Evdokimov
“It is very important to understand that apophatic theology, unlike agnosticism, is a particular way of “knowing through nonknowing.” It is the divine darkness conceived as a positive experience of God as the Existing One.

Contemplation is therefore placed beyond discourse. The suspension of all cognitive, cataphatic activity culminates in hesychia, that is, the silent inner concentration, the gathering together of one’s inner forces where “peace goes beyond all peace“
