Do not disregard your conscience, which always counsels you of the best. It puts before you divine and angelic advice; it frees you from the hidden stains of your heart, and will make you the gift of free speech with God at the time of your departure.
Conscience in men is nothing else but the voice of the omnipresent God moving in the hearts of men, as He Who alone Is and has created everything, the Lord knows all as Himself - all the thoughts, desires, intentions, words, and works of men, present, past, and future. However far in front I may let my thoughts, my imagination, run He is there before me and I ever inevitably finish my course in Him, ever having Him as the witness of my ways. 'His eyes are open upon all the ways of the sons of men' (Jer 32:19). 'Whither shall I go from Thy Spirit, or whither shall I flee from Thy presence?' (Ps 139:7).
It is up to us now to either bury our conscience under the ground, or to have it shine forth and illuminate us if we obey it. When our conscience says to us, 'Do this,' and we treat it with contempt, or it says it again and we refuse, then we are trampling it down, burying it under ground. Thus, it cannot speak to us clearly because of the weight upon it.
We ought not to grieve or become irritated at anything because, by frequent vexation and irritability, we form the morally and physically very injurious habit of irritability, whilst by bearing opposition with equanimity we form the good and useful habit of enduring everything calmly and patiently.
As a general rule, decide whether a thing is permissible by the effect it produces within. Permit yourself what is constructive, but never what is destructive.
There is nothing more burdensome and grievous then when conscience accuses us in anything, and there is nothing dearer then calmness and approval of the conscience.
You ask for some way of completely eradicating irritability. The inclination to irritability is given us to use against sin, and we were never meant to use it against our fellow men. When we do, we act contrary to our true nature.
When God, using our conscience, calls us to righteousness and yet our self-will opposes Him, He respects our freedom and lets our own will be done; but then, alas, our minds grow dull, our will slack, and we commit iniquities without number. On the other hand, the fruits of the spirit are soon granted to them who follow the commandments of Christ our Lord.
In the eyes of God, it is always preeminently right that a man should spend himself in devising new means for spreading consolation to his subordinates, who are his charges.
Keep your conscience keen and bright, and refrain from hankering after, or expecting, consolation. Leave that to God. He knows when, where, and how to give it to you.
You can see that a city is prosperous by the wealth of goods for sale in the market. Land too we call prosperous if it bears rich fruit. And so also the soul may be counted prosperous if it is full of good works of every kind. But first of all it has to be farmed energetically. Then it must be watered by abundant streams of heavenly grace for it to bring forth fruit, some thirty fold, some sixty fold, and some a hundred fold. The soul only acquires goodness and the capacity of fulfilling its duties if it has the grace of God On the other hand, what is uglier or more disgusting than a soul given over to base passions? Look at the hot-headed person: he is like a wild beast. Consider the slave of lust or gluttony: who can bear the sight of him? Pity the victim of melancholy whose spirit is totally prostrated. It is for us to seek to acquire beauty so that the Bridegroom, the Lord, may welcome us into his presence and say, “You are utterly fair, my love, and there is no flaw in you.” (Song of Sol 4:7)
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.
