If you are a friend of Christ you should have as friends persons who are of benefit to you and contribute to your way of life. Let your friends be men of peace, spiritual brethren, holy fathers. It is of such that our Lord was speaking when He said: 'My mother and brethren are those who do the will of My Father who is in heaven.' (cf. Matt. 12:49-50).
In detachment, the spirit finds quiet and repose for coveting nothing. Nothing wearies it by elation, and nothing oppresses it by dejection, because it stands in the center of its own humility.
