Continually say the Prayer [of Jesus] intensely, with zeal, with longing; only thus does one become strong in soul. Avoid idle words by means of all sacrifice, for they weaken the soul and it does not have the strength to struggle.
Be attentive, my child, that you not judge any soul. For God steps aside from the one who judges his neighbor, and he falls, in order to learn to have sympathy for his sick brother.
Put aside bodily considerations when you stand in prayer, lest the bite of a flea, a gnat or a fly deprive you of the greatest gain afforded by prayer.
When we judge our brother, we censure ourselves in a great sin. When therefore, we shield our brother, God will also shield us from great sins. When we uncover our brother, we drive off the grace of God from over us and we are given over to fall into the same things, so that we learn that we are all weak and the grace of God carries us. Whoever guards his tongue, that one guards his soul from great sins and falls.
If you are enclosed within yourself through prayer, humility, and mourning, you will find a spiritual treasure -- only let pride and criticism be far from you.
Therefore silence, prayer, obedience; when you practice these virtues with the help of God, then you will know the light of Christ is within your soul.
Do not be always wanting everything to turn out as you think it should, but rather as God pleases; then you will be undisturbed and thankful in your prayer.
He who wishes to tear up the account of his sins and to be inscribed in the Divine book of the saved, can find for this purpose no better means than obedience.
A monk is he who wants to sleep and does not sleep, who wants to eat and does not eat, who wants to drink and does not drink. A monk is distinguished by ‘continual forcing of nature.’
