Mind is not soul, but a gift from God which saves the soul. A mind pleasing to God flows ahead of the soul and counsels it to scorn the temporal, material and corruptible, and to love blessings that are eternal, incorruptible and immaterial, so that, while living in the body, man should, with his mind, apprehend and contemplate the heavenly and the divine. In this way a God-loving mind is a benefactor and savior of the human soul.
Do not say...that one or two books is sufficient for instructing the soul. After all, even the bee collects honey not from one or two flowers only, but from many. Thus also he who reads the books of the Holy Fathers is instructed by one in faith or in right thinking, by another in silence and prayer, by another in obedience and humility and patience, by another in self-reproach and in love for God and neighbor; and, to speak briefly, from many books of the Holy Fathers a man is instructed in life according to the Gospel.
When a man gives God his secret things, that is, his mind and thoughts, not occupying himself elsewhere, nor wandering away, but putting constraint upon himself, then the Lord deems him worthy of mysteries, in greater sanctity and purity, and gives him heavenly food and spiritual drink
A certain priest, an unfortunate man who had no knowledge of divine experience like that of St. Silouan, said to another person, 'I wonder why they go to him, he does not read anything.' The other replied, 'He does not read anything, but he practices everything, unlike those who read a lot but do not do a thing.'
If we want to do something but cannot, then before God, Who knows our hearts, it is as if we have done it. This is true whether the intended action is good or bad.
Confirm yourself in this truth: that every Divine writing that is in agreement with the path of salvation instructs, teaches, chastises, and strengthens, that our path might be ever according to God.
You write that after Communion you felt well. Glory be to God, Who comforts our unworthiness. And as regards the fact that this soon passed, here also is seen His fatherly providence for us. For continual consolation enfeebles the soul and makes it slothful, or leads to even greater harm. That is why the Lord takes it away quickly and again makes us feel our weakness, our helplessness, and our sinfulness. We must humble ourselves more, reproach ourselves, offer repentance for our sins, and not desire consolations, but patiently endure what God allows. Dryness and cooling of fervor are also permitted on account of vainglory.
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.
In order to remain in vigilance, it is necessary to guard the freshness and brightness of the mind with all care. The mind becomes darkened from imprudent use of food, drink and sleep, from much talking, from distraction and from worldly cares. Attend to yourselves, said the Lord, be on your guard and take care that your hearts are never weighed down, dulled and depressed by self-indulgence, overeating and drinking, or worldly cares and pleasures, lest that day (the day of Christ's dread judgment, the last day of the world) catch you unawares. For it will spring like a trap upon all who are living on the face of the earth. So watch and pray at all times for the strength to escape or survive all that is going to happen, and to stand before the Son of Man.
We came from Palestine to Egypt and went to see one of the fathers. He offered us hospitality and we said, 'Why do you not keep the fast when visitors come to see you? In Palestine they keep it.' He replied, 'Fasting is always with me but I cannot always have you here. It is useful and necessary to fast, but we choose whether we will fast or not. What God commands is perfect love. I receive Christ in you and so I must do everything possible to serve you with love. When I have sent you on your way, then I can continue my rule of fasting. The sons of the bridegroom cannot fast while the bridegroom is with them; when he is taken away from them, then they will fast.'
Many do good actions, but neglect the mind; they know nothing of the spiritual contests, the victories and defeats. They neglect the mind which is the eye of the soul.
One must endeavor to read through the writings of the Fathers, and strive as much as possible, according to one’s strength, to fulfill what they teach, and in this fashion, little by little ascend from the ascetic life to the perfection of the contemplative.
