“With every word unspoken each moment comes undone.”

A Man From Lebanon: Nineteen Centuries Afterward
Jesus, The Son of Man (1928)
Context: Master, master singer,
Master of words unspoken,
Seven times was I born, and seven times have I died
Since your last hasty visit and our brief welcome.
And behold I live again,
Remembering a day and a night among the hills,
When your tide lifted us up.

Alexis (1929)
Context: Every silence is composed of nothing but unspoken words. Perhaps that is why I became a musician. Someone had to express this silence, make it render up all the sadness it contained, make it sing as it were. Someone had to use not words, which are always too precise not to be cruel, but simply music.

Source: The Beloved Returns (1939), Ch. 7
Context: Hold fast the time! Guard it, watch over it, every hour, every minute! Unregarded it slips away, like a lizard, smooth, slippery, faithless, a pixy wife. Hold every moment sacred. Give each clarity and meaning, each the weight of thine awareness, each its true and due fulfillment.
