1. If we are concerned with our salvation, there are many things the intellect can do in order to secure for us the blessed gift of humility. For example , it can recollect the sins we have commited in word, action and thought; and there are many other things which, reviewed in contemplation, contribute to our humility.
True humility is also brought about by meditating daily on the achievements of our brethren, by extolling their natural superiorities and by comparing our gifts with theirs. When the intellect sees in this way how worthless we are and how far we fall short of the perfection of our brethren, we will regard ourselves as dust and ashes, and not as men but as some kind of cur, more defective in every respect and lower than all men on earth.
2. ‘Just as it is impossible to fight battles without weapons, or to swim a great sea with clothes on, or to live without breathing, so without humility and the constant prayer to Christ it is impossible to master the art of inward spiritual warfare or to set about it and pursue it skillfully.’
3. ‘Indeed, our true task is always the same and is always accomplished in the same way: to call upon our Lord Jesus Christ with a burning heart so that His holy name intercedes for us.’ –
4. “Be watchful as you travel each day the narrow but joyous and exhilarating road of the mind, keeping your attention humbly in your heart , reproaching yourself, ready to rebut your enemies, thinking of your death and invoking Jesus Christ. You will then attain avision of the Holy of Holies and be illumined by Christ with deep mysteries. For in Christ “the treasures of wisdom and knowledge” are hidden, and in Him “the fulness of the Godhead dwells bodily” (Col. 2:3; 9). (Philokalia (I) , On Watchfulness and Holiness 29.)
