Restrain the excitable power of your soul by love; mortify the desiring power by self-mastery; give wings to the thinking power by prayer, and the light of your mind will never be dimmed.
It is, indeed, impossible for the mind not to be troubled by thoughts, but accepting them or rejecting them is possible for everyone who makes an effort...therefore we practice the frequent reading of Scripture, so that we may be open to a spiritual point of view. For this reason we frequently chant the psalms, so that we may continually grow in compunction. For this reason we are diligent in vigils, fasting, and praying, so that the mind which has been stretched to its limits may not taste earthly things but contemplate heavenly ones. When these things cease because negligence has crept in again, then, it is inevitable that the mind, by the accumulated filth of the vices, will soon turn in a carnal direction and fall.
One must train oneself in self-reproach, that is, always accuse oneself & not others in one’s mind, reproach oneself and not others, and with a severe distrust of oneself accuse oneself of the failings which are covered up by our self-love, accuse ourself of our inclinations to sin. He who has self-reproach has peace, writes Abba Dorotheos, & will never be disturbed. If to such a one there should occur an illness, a wrong, a vexation, or some similar misfortune, he ascribes everything to his own sins & thanks God. If such a one is punished or reprimanded by the superior, he accepts all this as good & accepts every severe word against himself without murmuring or talking back, as the judgment of God.
We must always pray to the Lord to tell us what to do, and the Lord will not let us go astray. Adam was not wise enough to ask the Lord about the fruit which Eve gave him, and so he lost paradise.
I wish I could persuade spiritual persons that the way of perfection does not consist in many devices, nor in much cogitation, but in denying themselves completely and yielding themselves to suffer everything for the love of Christ. And if there is failure in this exercise, all other methods of walking in the spiritual way are merely a beating about the bush, and profitless trifling, although a person should have very high contemplation and communication with God.
The first duty of a Christian, of a disciple and follower of Jesus Christ, is to deny oneself. To deny oneself means to give up one's bad habits, to root out of the heart all that ties us to the world; not to cherish bad desires and thoughts; to quench and suppress bad thoughts; to avoid occasions of sin; not to do or desire anything from self-love but to do everything out of love for God. To deny oneself means, according to the Apostle Paul, to be dead to sin and the world, but alive to God.
A prayer offered while one has any cause to reproach a fellow man is an impure prayer. There is only one whom the praying person may and must reproach, and that is himself. Without self-reproach, your prayer is as worthless as it is while you are reproaching someone else in your heart. Perhaps you ask: How can one learn this? The answer is: One learns it through prayer.
Therefore, let us force ourselves. Let us make a beginning and let us desire the good with all our heart. Because, even if we are not perfect, wanting to be, is the beginning of our salvation. From wanting we come, with God’s help, to struggling and from struggling one is helped in acquiring the virtues. This is why one of the fathers says, 'Give blood and receive spirit,' that is to say, 'Struggle and you will become accustomed to virtue.'
