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.
In the presence of an invisible spirit, the body becomes afraid; but in the presence of an angel, the soul of the humble is filled with joy. Therefore, when we recognize the presence from the effect, let us quickly hasten to prayer, for our good guardian has come to pray with us.
Do not be surprised that you fall every day, do not give up, but stand your ground courageously. And assuredly, the angel who guards you will honor your patience. While a wound is still fresh and warm, it is easy to heal; but old, neglected and festering ones are hard to cure, and require for their care much treatment, cutting, plastering and cauterization. Many from long neglect become incurable, but with God all things are possible.
Therefore, if you wish to conquer the passions, cut off the love of pleasure; but if you are pursuing food, you will spend a life in passions; the soul will not be humbled if the flesh is not deprived of bread. It is not possible to deliver the soul from perdition while protecting the body from unpleasantness.
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.
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.
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.
If the passions strike you from time to time, this should not distress you. We must continue the 'unseen warfare' all our lives. The battle itself is not a problem; there is trouble only if we become weak in it. If this does not happen, our spiritual life is in good order. The peace that is with you in battle bears witness to this. But we must beware that we do not feel a different kind of peace, the kind one feels when there is no battle. This kind of peace is dangerous. It indicates that the enemy has done away with open battle and wants to build an invisible and clever snare for us! In cases like this one must intensify one's usual vigilance and sobriety! Do not weaken in any way!
Have confidence in the compassion of our Creator. Reflect well on what you are now doing, and keep before you the things you have done. Lift up your eyes to the overflowing compassion of heaven, and while He waits for you, draw near in tears to our merciful Judge. Having before your mind that He is a Just Judge, do not take your sins lightly; and having also in mind that He is compassionate, do not despair. The God-Man gives man confidence before God.
