MEDITATE

"When it becomes impossible to meditate again,
meditate. If you get an idea, develop it,
but without excitement. Feed your mind with reading
and the liturgy, and if the darkness of your simple
prayer becomes too much of a tension -- or
degenerates into torpor or sleep -- relieve it
with a few vocal prayers or simple affections,
but do not stain yourself trying to get ideas
or feel fervor. Do not upset yourself with useless
efforts to realize the elaborate prospects
suggested by a conventional book of meditations."
