By keeping the Commandments the soul is purified and the mind too is enlightened, and starts to function as nature intended it to. 'The command of the Lord gives light and enlightens the eyes' (Ps. 19:8).

In the measure that we pay attention and take care to carry out what we hear, God will always enlighten us and make us understand His will.

A man obtains the fear of God if he has the remembrance of his unavoidable death and of the eternal torments that await sinners; If he tests himself every evening as to how he has spent the day, and every morning as to how he has spent the night, and if is not sharp in his relations with others.

Sin is one thing but instinctive reaction or passion is another. These are our reactions: pride, anger, sexual indulgence, hate, greed, and so on. The corresponding sins are the gratification of these passions: when a man acts and brings into corporeal reality those works which were suggested to him by his desires. It is impossible to exist without desires arising, but not to give way to them is by no means impossible.

When the devil looks at a man who sincerely desires not to sin, he is not so unintelligent as to suggest to him (as he would to a hardened sinner) that he go and commit fornication or go and steal. He knows we do not want that and he does not set out to tell us something we do not want to hear; but he finds out that little bit of self-will or self-righteousness and through that, with the appearance of well doing, he will do us harm.

Again, after his fall, God gave him an occasion to repent and to receive mercy but he kept his stiff-neck held high. He came to him and said "Adam, Where are you?" instead of saying "What glory you have left and what dishonor you have arrived at?" After that, He asked him "Why did you sin? Why did you transgress the commandment?" By asking these questions, He wanted to give him the opportunity to say, "Forgive me." However, he did not ask for forgiveness. There was no humility, there was no repentance, but indeed the opposite.

Not only should we observe moderation with food, but we must also abstain from every other sin so that just as we fast with our stomach, we should fast with our tongue. Likewise, we should fast with our eyes; i.e. not look at agitating things, not allow your eyes freedom to roam, not to look shamelessly and without fear. Similarly, arms and legs should be restrained from doing any evil acts.
