See then the wretchedness of thy soul, for as the Memory was something established and fixed upon God, so now it hath forgotten Him and seeketh its rest in the creatures, now in one creature and then in another, and never can find full rest, having lost Him in whom is full rest. So it is with the Understanding and the Will and affections, both which were pure in spiritual favour and sweetness but now is turned into a foul, beastly lust and liking in itself and in the creatures and in fleshly favours, both in the senses as in gluttony and lechery; and in the imagination, as in pride, vain-glory and covetousness, insomuch that thou canst do no good deed but it is defiled with vain-glory; nor canst thou easily make use of any of thy five senses cleanly upon anything that is pleasant, but thy heart will be taken and enflamed with a vain lust and liking of it, which putteth out the love of God from thy heart, so that no feeling of love or spiritual favour may come into it. (John Climacus)

Lust, selfishness, gluttony, lechery, pride, vain-glory and covetousness are real. They certainly emerge from being separate from God.

To focus our memory, will, and reason on God's nature, expression, and intention will bring us closer.

I am not, however, sure that finding "full rest" is God's intention for us. Perhaps Climacus means rest as in being grounded.

There are sixteen Greek words that we translate as rest. I don't know which one Climacus used.

εἰρήνη or eirene captures my own sense of God's intention. Often translated as harmony or peace, it was for the Greeks the outcome of active engagement. The Greek goddess Eirene was usually shown carrying a cornucopia (prosperity), scepter, (good order), and a torch (enlightenment). She was one of three goddesses who created the potential for a good life.
