So long as the soul is sick with passions, its senses have no perception of the spiritual; and the soul does not even know how to desire it, but desires it only from hearsay and writings. The power of the soul is cured of these diseases by the hidden practice of commandments, with sharing in Christ's passion.
To be a righteous man among the righteous is a great and praiseworthy thing. But it is a far greater and more praiseworthy thing to be a righteous man among the unrighteous.
When a passion arises, when it is young and feeble, cut it off, lest it stiffen and cause you a great deal of trouble. It is one thing to pluck out a small weed and quite another thing to uproot a great tree.
Even if thy soul should suffer somewhat from an offense, keep the sorrow within thyself. For it is said: 'Within me my heart is troubled' (Psalm 142:4), that is, the passion has not come out, but has been humbled like a wave that has broken up on the shore. Calm thy raging heart. Let thy passions be ashamed at the presence of reason in thee, as playful children are ashamed before a man commanding respect.
If the main goal of the repentant sinner should be total, light-bearing and blessed communion with God, then the main hindrance to this is the existence of the passions still active and working in him - the virtues being as yet unsealed in him - and the unrighteousness of his powers. Therefore his main work upon conversion and repentance should be the uprooting of the passions and sealing the virtues - in a word, correcting himself.
What does it mean to be as wise as a serpent? When a serpent is attacked, it is willing to have much of its body severed, as long as it saves the head. So to be wise as a serpent means to be willing to lose everything - your wealth, your reputation, your friends - as long as you save your faith. Your faith is your head, by which you learn all truth; and by that truth your soul is set free. We should, however, recognize that the wisdom of the serpent is not enough; we must be honest and innocent as doves. Indeed it is the combination of wisdom and innocence that creates virtue. The person who is wise as a serpent can sustain the most terrible attacks and still continue to flourish as a disciple of Christ. The person who is innocent refuses to retaliate against those who make the attacks. To be as innocent as a dove means never to take revenge on those who wrong you or undermine you. Unless wisdom is tempered by innocence, one attack provokes another, and conflict continues without end. Unless innocence is tempered by wisdom, a person is so vulnerable that he will not even survive a single attack. Rest assured that no one can ever take away your faith; your wisdom guards against that. But be careful never to bear a grudge against anyone who does you wrong.
One must clean the royal house from every impurity and adorn it with every beauty, then the king may enter into it. In a similar way one must cleanse the earth of the heart and uproot the weeds of sin and the passionate deeds and soften it with sorrows and the narrow way of life, sow in it the seed of virtue, water it with lamentation and tears, and only then does the fruit of dispassion and eternal life grow. For the Holy Spirit does not dwell in a man until he has been cleansed from passions of the soul and body. Only one thing may remain within a man, either the Holy Spirit or the passions. Where the Holy Spirit is, there the passions do not come near, and where the passions are, there the Holy Spirit does not dwell, but rather the evil one.
If we cut off the causes of the passions for only a short while, and occupy ourselves with spiritual contemplation without making it our sole and constant concern, we easily revert to the passions of the flesh, gaining nothing from our labor but theoretical knowledge coupled with conceit. The result is a gradual darkening of this knowledge itself and a complete turning of the intellect towards material things.
If Nabuzardan, the court cook of the King of the Babylonians, had not gone to Jerusalem, then the Temple would not have burned (cf. 2 Kings 24), That is to say, a person’s mind is not attacked by the flames of carnal pleasures, if a person is not conquered by gluttony.
