The more a man's tongue flees verbosity, the more his intellect is illumined so as to be able to discern deep thoughts; for the rational intellect is befuddled by verbosity.
You know that evil entered into us through the transgression of the commandments. Hence it is obvious that by keeping them, evil departs from us. But without the doing of the commandments we should not even aspire or hope for purity of soul, because at the very outset we do not walk on the path that leads us to purity of soul. Do not say that God can give us the grace of purity of soul even without our keeping the commandments.

We are told to draw the waters of life from the sources of the Divine Writings which alone can extinguish the passions that plague us and set us on the road to intellectual truth.
Do not oppose the thoughts, which the enemy sows in you, but rather cut off all converse with them by prayer to God. We have not always strength enough so to oppose hostile thoughts as to stop them; on the contrary, in such attempts they frequently inflict us with a wound that is long in healing.
As a man whose head is under water cannot inhale pure air, so a man whose thoughts are plunged into the cares of this world cannot absorb the sensations of that new world.
When you ae conscious of the sweetness of divine grace working in you and when prayer operates in your heart, then you must continue in it. Do not interrupt it or rise up to sing psalms as long as God sees fit to leave its work in you, for to do so would be to leave God who is within, in order to call on Him outside yourself, as if one were to leave the heights to stoop down to the flats.
When I wish to open my mouth and to speak on the exalted theme of humility, I am filled with dread, like someone who is aware that he is about to discourse with his own imperfect words concerning God.
