Remember me, ye heirs of God, ye brethren of Christ, supplicate the Saviour earnestly for me, that I may be freed though Christ from him that fights against me day by day.
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.
Beware of the counsels of the evil one, if he should come in the guise of one professing truth to beguile you and lead you into deceit. Even if he should come to you as an angel of light, do not believe him or obey him: for he is apt to fascinate the faithful by the attractive semblance of truth.
If the mind is strengthened with the strength that it received from the Spirit, first it is purified and sanctified, and learns discrimination in the words that it delivers to the tongue, that they may be without partiality and without self-will, and so the saying of Solomon is fulfilled, `My words are spoken from God, there is nothing forward nor perverse in them.' (Cf. Prov. 8:8) And in another place he says, `The tongue of the wise is healing' (Prov. 12:18), and much besides.
Mind is not soul, but a gift from God which saves the soul. A mind pleasing to God flows ahead of the soul and counsels it to scorn the temporal, material and corruptible, and to love blessings that are eternal, incorruptible and immaterial, so that, while living in the body, man should, with his mind, apprehend and contemplate the heavenly and the divine. In this way a God-loving mind is a benefactor and savior of the human soul.
If we use all means and all efforts to avoid death of the body, how much more must we seek to avoid death of the soul. For there is no obstacle for a man wishing to be saved, except negligence and laziness of soul.
When you close the doors to your dwelling and are alone you should know that there is present with you the angel whom God has appointed for each man...This angel, who is sleepless and cannot be deceived, is always present with you; he sees all things and is not hindered by darkness. You should know, too, that with him is God, who is in every place; for there is no place and nothing material in which God is not, since He is greater than all things and holds all men in His hand.
Those who have sinned must not despair. Let that never be. For we are condemned not for the multitude of evils, but because we do not want to repent...
