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.
A life of spiritual endeavor is the mother of sanctity; from it is born the first experience of perception of the mysteries of Christ--which is called the first stage of spiritual knowledge.
Just as we must beware of overeating, so too we must beware of excessive temperance or abstinence. Excessive temperance weakens the body, destroys wakefulness, coolness and freshness which are indispensable for vigilance, and which fade and weaken when the physical powers succumb and fail. If you force a weak body to labor beyond its powers, you subject your soul to double darkness, and lead it into confusion (and not relief)...
Not every man is wakened to wonder by what is said spiritually and has great power concealed in it. A word concerning virtue has need of a heart unbusied with the earth and its converse.
On that day God will not judge us about psalmody, nor for the neglect of prayer, but because by abandoning them, we have opened our door to the demons.
As a man cannot remain unscathed who spares his enemy on the field of battle, so a man engaged in spiritual warfare cannot save his soul if he spares his body.
Be despised and rejected in your own eyes, and you will see the glory of God within yourself. For where humility blossoms, there God’s glory bursts forth.
