BROTHER: Behold, through what have the men of old triumphed? OLD MAN: Through the fervor of their supernatural love, and through the death of the corruptible man, and through the contempt for pride, and through the abatement of the belly, and through the fear of the judgement, and through the promise of certainty; through the desire for these glorious things the fathers have acquired in the soul the spiritual body.
At your work, flee conversation; only measured words in case of need. The hands should work for the needs of the body, and the mind should say the sweetest name of Christ, so that the need of the soul, which we must not forget even for moment, also will be provided for.
And the old man also said, 'God saith unto thee thus -- if thou lovest Me, O monk, do that which I ask, and do not that which I do not desire. For monks should lead lives wherein they act not in iniquity, and a man should not look upon evil things with his eyes, no hear with his ears things which are alien to the fear of God, nor utter calumnies with his mouth, nor plunder with his hands; but he should give especially to the poor, and he should not be unduly exalted in his mind, and he should not think evil thoughts, neither should he fill his belly. Let him do then all these things with discretion, for by them is a monk known.' The old man also said, 'These things form the life of a monk: good works, and obedience, and training. A man should not lay blame on his neighbor, and he should not utter calumnies, and he should not complain, for it is written, 'The lovers of the Lord hate wickedness.'
The brothers said, 'Why is it that the monks are obliged to go around begging for the food and clothes they need, like those who are in the world, although our Lord promised them, saying, ‘Seek ye first the kingdom of God and its righteousness, and that of which ye have need shall be given to you’ (Matt. 6:23)?' The old man said, 'This saying is a proof of the wisdom and grace of God toward those who are in the world, for in the majority of cases, the righteousness of the children of this world consists of alms and compassion; but the children of light are righteous people and monks who, in their persons, and in their bodies, and in their thoughts, serve our Lord. And God has made the monks to have need of the children of this world because of His love, so that they may care for each other, and may pray for each other; that is to say, the children of the world must care for the monks and the monks must pray in love for them. And as the children of the world make the monks associates with them in the corporeal things of the world, the monks must make the children of the world to be associates with them in the things of heaven, for our Lord spoke to the children of the world, saying, ‘Make ye to yourselves friends of this mammon of iniquity so that when they have become perfect they may receive you into their tabernacles which are forever.’ (Luke 14:9)
Therefore silence, prayer, obedience; when you practice these virtues with the help of God, then you will know the light of Christ is within your soul.
You write that after Communion you felt well. Glory be to God, Who comforts our unworthiness. And as regards the fact that this soon passed, here also is seen His fatherly providence for us. For continual consolation enfeebles the soul and makes it slothful, or leads to even greater harm. That is why the Lord takes it away quickly and again makes us feel our weakness, our helplessness, and our sinfulness. We must humble ourselves more, reproach ourselves, offer repentance for our sins, and not desire consolations, but patiently endure what God allows. Dryness and cooling of fervor are also permitted on account of vainglory.
