The more a man hath unity and simplicity in himself, the
more things and the deeper things he understandeth; and that
without labor, because he receiveth the light of understanding
from above. The spirit which is pure, sincere and steadfast,
is not distracted though it hath many works to do, because it
doth all things to the honor of God, and striveth to be free
from all thoughts of self-seeking.
... Thomas a Kempis (1380-1471), Of the Imitation of
Christ [1418]
