When your brother is disturbed and reacts to what you say to him, control your tongue lest you speak even one word in wrath and do not allow yourself to be arrogant concerning him in your heart but remember that he is your brother, a member of Christ and an image of God, influenced by the common enemy. Be merciful and show pity on him because it is possible that the devil through your wrath, will capture his soul and mortify it in resentment and thus, through your carelessness, the soul for whom Christ died is lost (1 Cor. 5:11).
As a man cannot remain unscathed who spares his enemy on the field of battle, so a man engaged in spiritual warfare cannot save his soul if he spares his body.
A small affliction borne for God's sake is better [before God] than a great work performed without tribulation, because affliction willingly borne brings to light the proof of love.
Love sinners, but hate their works, and do not despise them for their faults, lest you be tempted by the same. Remember that you share the earthly nature of Adam and that you are clothed with his infirmity.
If you pile up on one side of the scales all the works demanded by ascetic life, and on the other side-silence, you will find that the latter outweighs the former. Many good counsels have been given us, but if a man embraces silence, to follow them will become superfluous.
If a man has a friend and he is absolutely certain that his friend loves him, and if that friend does something to cause him suffering and be troublesome to him, he will be convinced that his friend acts out of love and he will never believe that his friend does it to harm him. How much more ought we to be convinced about God who created us, who drew us out of nothingness to existence and life, and who became a man for our sake and died for us, and who does everything out of love for us?
I have heard about a certain brother that when he was visiting one brother if he saw his cell untidy and neglected, he would say to himself, 'This brother is blessed because he has achieved freedom from care about all these earthly things. So, he has lifted up his entire nous to God so that he does not interrupt his spiritual work to put his cell in order.' If he afterwards went to another brother and saw his cell tidy, clean and in good order, he would say to himself, 'As this brother’s soul is clean, so also is his cell. The state of his cell corresponds with the state of his soul.' He never said about anybody that he is slovenly or vainglorious. Since he himself was in a good spiritual state, he drew profit from each case. May God grant us a good spiritual state so that we also can be profited and never think anything evil about our neighbor. Even if sometimes it happens that we think or suspect something bad about our brother, let us immediately transform our thought into a good one. The not seeing the evil of the neighbor, produces, with God’s help, goodness.
Prayer offered up at night possesses a great power, more so than the prayer of the day-time. Therefore all the righteous prayed during the night, while combating the heaviness of the body and the sweetness of sleep and repelling bodily nature.
