A passion is a contranatural movement of the soul or an irrational love, or an blindfold hatred toward any material thing, or because of it: for example, for food, or for women, or for riches, or for worldly glory, or any other sensible thing; or for the sake of such things, as in a senseless hatred for someone on account of the things mentioned above.
Maximus the ConfessorWhatever a man loves he inevitably clings to, and in order not to lose it he rejects everything that keeps him from it. So he who loves God cultivates pure prayer, driving out every passion that keeps him from it. He who drives out self-love, the mother of the passions, will with God's help easily rid himself of the rest, such as anger, irritation, rancor and so on. But he who is dominated by self-love is overpowered by the other passions, even against his will. Self-love is the passion of attachment to the body.
Maximus the ConfessorThe mind of a man that loves God does not fight against things or thoughts about them, but against the passions that are connected with these thoughts. That is, he does not struggle against a woman, or against one who has insulted him, and not against the images of them, but against the passions that are aroused by these images.
Maximus the ConfessorDo not disdain the commandment to love, for through it you become a son of God, and when you break it, you become a son of Gehenna.
Maximus the ConfessorIf you are remembering evil against someone, then pray for him; and as you remove through prayer the pain of the remembrance of the evil he has done, you will stop the advance of the passion. And when you have attained brotherly love and love for mankind, you will completely cast this passion out of your soul. Then when someone else does evil to you, be affectionate and humble toward him, and treat him kindly, and you will deliver him from this passion.
Maximus the Confessor'The long-suffering man abounds in understanding' (Prov. 14:29), because he endures everything to the end and, while awaiting that end, patiently bears his distress. The end, as St. Paul says, is everlasting life (cf. Rom. 6:22). 'And this is eternal life, that they might know You the only true God, and Jesus Christ whom You have sent' (Jn. 17:3).
