On inner peace.
Inner peace is acquired through sorrows. The Scriptures say: We went through fire and through water; but Thou has brought us out into a tranquil place (Psalm 66:12). For those who wish to please God, the path lies through many sorrows. How can we worship the holy martyrs for the suffering they endured for the sake of God, when we ourselves are unable to endure even a single spark? Thus we must concentrate all our thoughts, wishes and actions towards attaining the peace of God. We must do our best to preserve this inner peace and not become upset by insults on the part of others; to this end we must make a great effort to restrain our anger, and by means of attentiveness safeguard our mind and heart from unseemly actions. Therefore, we must be totally indifferent to insults from others, and we must attain such a disposition whereby these insults would seem to us to concern others and not ourselves…
