...just as the edifice of all the virtues strives upward toward perfect prayer so will all these virtues be neither sturdy nor enduring unless they are drawn firmly together by the crown of prayer. This endless, unstirring calm of prayer... can neither be achieved nor consummated without these virtues. And likewise virtues are the prerequisite foundation of prayer and cannot be effected without it.

Fasts and vigils, the study of Scripture, renouncing possessions and everything worldly are not in themselves perfection, as we have said; theyare its tools. For perfection is not to be found in them; it is acquired through them. It is useless, therefore, to boast of our fasting, vigils, poverty, and reading of Scripture when we have not achieved the love of God and our fellow men. Whoever has achieved love has God within himself and his intellect is always with God.

God can be sensed when we gaze with trembling hearts at that power of his which controls, guides, and rules everything, when we contemplate his immense knowledge and his knowing look which the secrets of the heart cannot evade.

...whoever is guided solely by his own judgment and decision will never climb up to the summit of perfection and will not fail to be the victim of the devil's ruinous power to delude.

A clear rule for self-control handed down by the Fathers is this: stop eating while still hungry and do not continue until you are satisfied.

... a Christian is quite certain to fall into the same sins which he condemns in another with merciless and inhuman severity, for 'a stern king will fall into misfortunes,' and 'one who stops his ears so as not to hear the weak, shall himself cry, and there shall be none to hear him' (Prov. 13:17; 21:13).

The bond between friends cannot be broken by chance; no interval of time or space can destroy it. Not even death itself can part true friends.
