The one who through asceticism and contemplation has known how to dig in himself the wells of virtue and knowledge as did the patriarchs will find Christ within as the spring of life. Wisdom bids us to drink from it, saying, 'Drink waters from your own vessels and from your own springs'. If we do this we shall discover that His treasures are present within us.
If you harbor rancor against anybody, pray for him and you will prevent the passion from being aroused; for by means of prayer you will separate your resentment from the thought of the wrong he has done you. When you have become loving and compassionate towards him, you will wipe the passion completely from your soul.
The one who engages in a pursuit of wisdom out of devotion and stands prepared against the invisible forces should pray that both the natural discernment (with its proportionate light) and the illuminating grace of the Spirit remain with him. The former trains the flesh in the acquisition of virtue through asceticism while the latter illuminates the mind to select the companionship of wisdom before all others, according to the Scripture, 'He works the destruction of the strongholds of evil & of every pretension which raises itself up against the knowledge of God' (2 Cor. 10:5).
He who like Job and the courageous martyrs bears the assaults of unsought-for trials and temptations with an unshakeable will is a powerful lamp; for by his bravery and patience he keeps the light of salvation burning, since he possesses the Lord as his strength and his song. (cf. Ps. 118: 14).
Unless curbed by the fear of God that accompanies the practice of the virtues, spiritual knowledge leads to vanity; for it encourages the person puffed up by it to regard as his own what has merely been lent to him, and to use his borrowed intelligence to win praise for himself. But when his practice of the virtues increases concomitantly with his longing for God, and he does not arrogate to himself more spiritual knowledge than is needed for the task in hand, then he is made humble, reduced to himself by principles which are beyond his capacity.
Do not disregard your conscience, which always counsels you of the best. It puts before you divine and angelic advice; it frees you from the hidden stains of your heart, and will make you the gift of free speech with God at the time of your departure.
There are three things that move us to the good: natural tendencies, the holy Powers, good choice. The natural tendencies - as, for instance, when what we wish men would do for us, we likewise do for them; or, when we see someone in sore straits, we then naturally have pity. The holy Powers - as when moved to some fine deed, we experience their good assistance and prosper. Good choice - when, for example, discerning good from evil, we choose the good.
Almsgiving heals the soul's incensive power; fasting withers sensual desire; prayer purifies the intellect and prepares it for contemplation of created beings. For the Lord has given us commandments which correspond to the powers of the soul.
The one who prays ought never to halt his movement of sublime ascent toward God. For just as we should understand the ascent 'from strength to strength' as the progress in the practice of the virtues, 'from glory to glory' (2 Cor. 3:18) as the advance in the spiritual knowledge of contemplation, and the transfer from the letter of sacred writing to its spirit, so in the same way the one who is settled in the place of prayer should lift his mind from human matters and the attention of the soul to more divine realities.
It is not food that is evil but gluttony; not childbearing but fornication; not money but cupidity; not glory but vainglory. If this be so there is no evil in anything that is, except wrong use, which results from our mind neglecting to cultivate our nature (the powers of the soul, and their right direction).
Do we forgive our neighbors their trespasses? God also forgives us in His mercy. Do we refuse to forgive? God, too, will refuse to forgive us. As we treat our neighbors, so also does God treat us. The forgiveness, then, of your sins or unforgiveness, and hence also your salvation or destruction, depend on you yourself, man. For without forgiveness of sins there is no salvation. You can see for yourself how terrible it is.
