Spiritual activity embodies Christ in our soul. This involves continual remembrance of the Lord: you hide Him within, in your soul, your heart, your consciousness.
In detachment, the spirit finds quiet and repose for coveting nothing. Nothing wearies it by elation, and nothing oppresses it by dejection, because it stands in the center of its own humility.
Fire and water do not mix, neither can you mix judgment of others with the desire to repent. If a man commits a sin before you at the very moment of his death, pass no judgment, because the judgment of God is hidden from men. It has happened that men have sinned greatly in the open but have done greater deeds in secret, so that those who would disparage them have been fooled, with smoke instead of sunlight in their eyes.
Let us observe and we shall find that the spiritual trumpet serves as an outward signal for the gathering of the brethren, but it is also the unseen signal for the assembly of our foes. So some of them stand by our bed, and when we get up urge us to lie down again: 'Wait,' they say, 'till the preliminary hymns are finished; then you can go to church.' Others plunge those standing at prayer into sleep. Some produce severe, unusual pains in the stomach. Others urge us on to make conversation in church. Some entice the mind to shameful thoughts. Others make us lean against the wall as though from fatigue. Sometimes they involve us in fits of yawning. Some of them bring on waves of laughter during prayer, thereby desiring to stir up the anger of God against us. Some force us to hurry the reading or chanting merely from laziness; others suggest that we should chant more slowly for the pleasure of it; and sometimes they sit at our mouths and shut them, so that we can scarcely open them. He who reckons with feeling of heart that he stands before God in prayer shall be an unshakeable pillar, and none of the aforesaid demons will make sport of him.
Think also of this: the person who is bound to earthly things may rejoice but may also be upset or disturbed or grieved over earthly things: his mind is exposed to continual changes. But the joy of your master (Matthew 25:21) is enduring, for God is unchangeable. Thus control your tongue at the same time as you discipline your body with fasting and strictness. Talkativeness is a great enemy of prayer. A spate of fluttering words stands in the way of the words of prayer. This is the reason that we shall render account for every careless word we utter (Matthew 12:36). One does not bring the dust of the road into a room that one wishes to keep clean; thus keep your heart free from gossip and chatter about the events of the day that is past.
Wrath is a reminder of hidden hatred, that is to say, remembrance of wrongs. Wrath is a desire for the injury of the one who has provoked you. Irascibility is the untimely blazing up of the heart. Bitterness is a movement of displeasure seated in the soul. Anger is an easily changeable movement of one’s disposition and disfiguration of soul.
True joy is the joy of consolation, the joy that wells up in the knowledge of one's own weakness and the Lord's mercy, and that does not need the bared teeth of laughter to express itself.
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.
