When thou comest by thyself,
think not before what thou shalt do after,
but forsake as well good thoughts as evil thoughts,
and pray not with thy mouth
but list[en] thee right well.
And then if thou aught shalt say,
look not how much nor how little that it be,
nor weigh not what it is nor what it bemeaneth …
and look that nothing live in thy working mind
but a naked intent stretching into God,
not clothed in any special thought of God in Himself … .
This naked intent freely fastened and grounded in very belief
shall be nought else to thy thought and to thy feeling
but a naked thought and a blind feeling of thine own being:
as if thou saidest thus unto God, within in thy meaning,
“That what I am, Lord, I offer unto Thee,
without any looking to any quality of Thy Being,
but only that Thou art as Thou art, without any more.”
That meek darkness be thy mirror, and thy whole remembrance.
Think no further of thyself than I bid thee do of thy God,
so that thou be one with Him in spirit,
as thus without departing and scattering,
for He is thy being, and in Him thou art that thou art;
not only by cause and by being, but also,
He is in thee both thy cause and thy being.
— Anonymous, Epistle of Privy Counsel.
For silence is not God, nor speaking is not God;
fasting is not God, nor eating is not God;
loneliness is not God, nor company is not God;
nor yet any of all the other two such contraries.
He is hid between them, and may not be found
by any work of thy soul,
but all only by love of thine heart.
He may not be known by reason,
He may not be gotten by thought,
nor concluded by understanding;
but He may be loved and chosen
with the true lovely will of thine heart … .
— Anonymous, Epistle of Discretion.
On the art of contemplative prayer; that is, of love meeting love.
PSALMISTICE 
These verses seem to resonate somewhat, I feel —
Matthew 6:1-8New King James Version (NKJV)
Do Good to Please God
6 “Take heed that you do not do your charitable deeds before men, to be seen by them. Otherwise you have no reward from your Father in heaven. 2 Therefore, when you do a charitable deed, do not sound a trumpet before you as the hypocrites do in the synagogues and in the streets, that they may have glory from men. Assuredly, I say to you, they have their reward. 3 But when you do a charitable deed, do not let your left hand know what your right hand is doing, 4 that your charitable deed may be in secret; and your Father who sees in secret will Himself reward you openly.[a]
The Model Prayer
5 “And when you pray, you shall not be like the hypocrites. For they love to pray standing in the synagogues and on the corners of the streets, that they may be seen by men. Assuredly, I say to you, they have their reward. 6 But you, when you pray, go into your room, and when you have shut your door, pray to your Father who is in the secret place; and your Father who sees in secret will reward you openly.[b] 7 And when you pray, do not use vain repetitions as the heathen do. For they think that they will be heard for their many words.
8 “Therefore do not be like them. For your Father knows the things you have need of before you ask Him.
