Join to every breath a sober invocation of the name of Jesus and the thought of death with humility. Both these practices bring great profit to the soul.
One of the Fathers said: just as it is impossible for a man to see his face in troubled water, so too the soul, unless it be cleansed of alien thoughts, cannot pray to God in contemplation.
He who wishes to tear up the account of his sins and to be inscribed in the Divine book of the saved, can find for this purpose no better means than obedience.
If a king wanted to take possession of his enemy's city, he would begin by cutting off the water and the food and so his enemies, dying of hunger, would submit to him. It is the same with the passions of the flesh; if a man goes about fasting and hungry the enemies of his soul grow weak.
Anger is by nature designed for waging war with the demons and for struggling with every kind of sinful pleasure. Therefore angels, arousing spiritual pleasure in us and giving us to taste its blessedness, incline us to direct our anger against the demons. But the demons, enticing us towards worldly lusts, make us use anger to fight with men, which is against nature, so that the mind, thus stupefied and darkened, should become a traitor to virtues.
For the washing away of bodily dirtiness God has given water. And for the washing of spiritual foulness, God has given the grace of the holy Sacrament of Confession. Every man, when he dirties his hands, washes them. No one says, 'I will not wash my hands anymore, because I will get them dirty again!' But why is it then that many people say, 'I will not go to Confession, because I will not sin again tomorrow!' It is clear that the enemy of our salvation is enticing us not to wash our souls, so that he can gain power over them.
