The eye of human vision does not discern the good which he is doing. The way to perfection is through the realization that we are blind, poor, and naked. This sense of nakedness is closely linked with contrition of the spirit, when in unceasing repentance we pour out before God our grief and sorrow at our impurity. Penitent feelings are an essential element of true spiritual progress, and whoever evades them is deviating from the right way. On reaching spiritual maturity man becomes acutely conscious of his sinfulness and corruption, and his sense of contrition and repentance grows ever more profound.
Tears are the measure of progress, and unceasing tears are a sign of coming purification.
In this way, learn to know yourself. If some thought emerges more often than others, it signifies a passion stronger than the rest. This means that you must combat it with greater energy. Yet do not place any reliance on yourself and do not expect to achieve anything by your own efforts. All means of healing and all remedies are sent by the Lord.
