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.
To more conveniently become accustomed to remembering God, the fervent Christian has a special means, namely, to repeat ceaselessly a brief prayer of two or three words. Mostly this is 'Lord, have mercy.' or 'Lord Jesus Christ, Son of God, have mercy on me, a sinner.' If you have not yet heard of this, then hear it now, and if you have not done it, then begin from this hour to do it.
When the intellect is pure, sometimes God Himself approaches and teaches it; and sometimes the angelic powers, or the nature of the created things that it contemplates, suggests holy things to it.
Almsgiving heals the soul's incensive power; fasting withers sensual desire; prayer purifies the intellect and prepares it for contemplation of created beings. For the Lord has given us commandments which correspond to the powers of the soul.
Do not befoul your intellect by clinging to thoughts filled with anger and sensual desire. Otherwise you will lose your capacity for pure prayer and fall victim to the demon of listlessness.
But there is hardly anything more serious than to be joined in marriage to a stranger (i.e., to an unbeliever), where the instigations both of lustful appetite and of disharmony and the shameful crimes of sacrilege are welded together. For if marriage itself needs to be sanctified by the priestly veil and blessing, how is it possible to speak of a marriage where there is no agreement in faith?
Let your very dress urge you to the work of mourning, because all who lament the dead are dressed in black. If you do not mourn, mourn for this cause. And if you mourn, lament still more that, by your sins, you have brought yourself down from a state free of labors to one of labor.
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.
Meekness is the fellow-worker of obedience, the guide of the brotherhood, a bridle for the enraged, a check to the irritable, a minister of joy, the imitation of Christ, something proper to angels, shackles for demons, a shield against bitterness.
In everything we do, God looks as the aim, whether it is for Him or for some other purpose we act. So, when we wish to do something good, let us have as our aim not to please men but to please God, so as to have our eyes always fixed on Him, doing everything for Him, lest we bear the labor but lose the reward.
