He who has been granted the grace of spiritual knowledge and yet harbors resentment, rancour or hatred for anybody, is like someone who lacerates his eyes with thorns and thistles. Hence knowledge must be accompanied by love.
Those who mourn and those who are insensitive are not subject to fear, but the cowardly often have become deranged. And this is natural. For the Lord rightly forsakes the proud that the rest of us may learn not to be puffed up.
There is nothing more burdensome and grievous then when conscience accuses us in anything, and there is nothing dearer then calmness and approval of the conscience.
Let no one on seeing or hearing something supernatural in the monastic way of life fall into unbelief out of ignorance; for where the supernatural God dwells, much that is supernatural happens.
Do not be surprised that you fall every day; do not give up, but stand your ground courageously. And assuredly, the angel who guards you will honor your patience.
A little fire softens a large piece of wax. So, too, a small indignity often softens, sweetens and wipes away suddenly all the fierceness, insensibility & hardness of our heart.
Some people living carelessly in the world have asked me: 'We have wives and are beset with social cares, and how can we lead the solitary life?' I replied to them: 'Do all the good you can; do not speak evil of anyone; do not steal from anyone; do not hate anyone; do not be absent from Divine services; do not offend anyone; do not wreck another man's domestic happiness, and be content with what your own wives can give you. If you behave in this way, you will not be far from the Kingdom of Heaven.'
If we cut off the causes of the passions for only a short while, and occupy ourselves with spiritual contemplation without making it our sole and constant concern, we easily revert to the passions of the flesh, gaining nothing from our labor but theoretical knowledge coupled with conceit. The result is a gradual darkening of this knowledge itself and a complete turning of the intellect towards material things.
Do not condemn today as base and wicked the man whom yesterday you praised as good and virtuous, changing love to hatred, because he has criticized you, but even though you are still full of resentment, commend him as before, and you will soon recover your same saving love.
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).
