The Cloud of Unknowing, ed. by Evelyn Underhill, [1922], at sacred-texts.com
That by indiscretion in this, men shall keep discretion in all other things; and surely else never
BUT peradventure thou askest me, how thou shalt govern thee discreetly in meat and in sleep, and in all these other. And hereto I think to answer thee right shortly: “Get that thou get mayest.” Do this work evermore without ceasing and without discretion, and thou shalt well ken begin and cease in all other works with a great discretion. For I may not trow that a soul continuing in this work night and day without discretion, should err in any of these outward doings; and else, me think that he should always err. p. 206
And therefore, an I might get a waking and a busy beholding to this ghostly work within in my soul, I would then have a heedlessness in eating and in drinking, in sleeping and in speaking, and in all mine outward doings. For surely I trow I should rather come to discretion in them by such a heedlessness, than by any busy beholding to the same things, as I would by that beholding set a mark and a measure by them. Truly I should never bring it so about, for ought that I could do or say. Say what men say will, and let the proof witness. And therefore lift up thine heart with a blind stirring of love; and mean now sin, and now God. God wouldest thou have, and sin wouldest thou lack. God wanteth thee; and sin art thou sure of. Now good God help thee, for now hast thou need! p. 207
