St. Seraphim of Sarov: On Spiritual Peace

 We can see how to defeat anger in the life of St. Paisius the Great. He asked the Lord Jesus Christ, Who appeared to him, to release him from anger. But Christ answered him, "If you want to defeat anger and wrath together, desire nothing, hate no one, humiliate no one."¹To preserve peace of soul you must keep despair at bay and try to preserve a joyful disposition, not a sorrowful one. As the wise Sirach said, "For sorrow has destroyed many, and there is no profit in it" (Sirach 30:23). To preserve peace of soul, you must in every way avoid condemnation of others. By you lack of judgment and your silence, you will preserve spiritual peace. When a man is in such a state, he receives divine revelations.

St. Seraphim of Sarov: Do not Judge your Neighbor

We must not Judge anyone, even if with our own eyes we have seen someone sinning, or walking in transgression of God's commandments. For according to the word of God: "Judge not, that ye be not judged" (Matt 7:1), and again: "Who art thou that judgest another man's servant? To his own master he standeth of falleth; yea, he shall be holden up: for God is able to make him stand" (Rom 14:4).
It is much better always to bring to mind these words of the Apostle: "Let him that thinkest he standeth take heed lest he fall" (1 Cor 10:12).
For we do not know how long we may remain in virtue, as says the Prophet who attained to knowledge of this matter by experience: "In my prosperity I said, I shall never be moved. Thou didst hide Thy face, and I am troubled" (Ps 29:7-8).

St. Seraphim of Sarov: On Preserving Spiritual Peace

It is necessary to strive to preserve one's spiritual peace by any means possible. Do not be upset by the insults of others. Strive in every possible way to restrain yourself from anger and to guard attentively both your heart and mind against unbefitting emotions.
Therefore tolerate the insults of others with equanimity and try to preserve your disposition as if these were not directed at you. Such and exercise will bring peace to your heart and prepare it as an abode for God Himself.
We see an example of such forbearance in the life of St. Gregory the Wonderworker, when a certain prostitute publicly demanded that he compensate her for an alleged sinful encounter with her. He, not becoming in the least angry, meekly told his friend to give her the money she was demanding. The woman had no sooner taken the money than she fell subject to an attack of a demon. Then the holy one prayed and drove the demon from her.
If on the other hand, you find it impossible not to become offended, then at least you should try to hold your tongue, for as the Psalmist said, "I was troubled and did not speak."(Psalms 77:4)
