Every day you provide your bodies with good to keep them from failing. In the same way your good works should be the daily nourishment of your hearts. Your bodies are fed with food and your spirits with good works. You aren't to deny your soul, which is going to live forever, what you grant to your body, which is going to die.
If the soul is vigilant and withdraws from all distraction and abandons its own will, then the spirit of God invades it and it can conceive because it is free to do so.
The first divine fruit of silence is mourning -- grief according to God -- joy-grief. Afterward come luminous thoughts, which bring the holy flow of tears streaming with life, from which also comes the second baptism and the soul is purified and shines and becomes like the angels.
Our soul is simple as thought, and rapid as thought or lightning. In an instant it can be wounded by sin and become attached to corruptible things; in an instant it can fall away from the love of God and its neighbor through a single unrighteous thought, through a single passionate desire, through a single malevolent thought, and, therefore, we must constantly watch our heart, lest it should incline to words or thoughts of evil, and must ever strive to preserve it in God's simplicity and purity, and in the love of God and its neighbor.
When a man has been sufficiently illumined, however, to perceive his own faults, he never ceases mourning for himself and for all men, seeing God’s great forbearance and what sins we in our wretchedness have committed and still persist in committing. As a result of this he becomes full of gratitude, not daring to condemn anyone, shamed by the profusion of God’s blessings and the multitude of our sins. Thereupon he joyfully renounces everything in his own will that is counter to God, and he watches over his own senses, so as to prevent them from doing anything beyond what is unavoidably needed.
Mourning has a twofold action: like water tears extinguish all the fire of passions and wash the soul clean of their foulness; and, again, through the presence of the Holy Spirit, it is like fire bringing life, warming the heart, and inciting it to love and desire God.
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.
If you possess the gift of mourning, hold on to it with all your might. For it is easily lost when it is not firmly established. And just as wax melts in the presence of fire, so it is easily dissolved by noise and bodily cares, and by luxury, and especially by talkativeness and levity.
Go to the tombs and see that the assurance of men is nothing. Why then does man who is dust indulge in vainglory? Why does he who is all stench exalt himself? Let us therefore weep for ourselves while we have time, lest, at the hour of our departure, we be found asking God for extra time to repent.
The body can neither love nor hate. Neither can a body fall in love with a body. The capability for love belongs to the soul. When the soul is in love with the body, that is not love but desire, lust. When the soul is in love with the soul, but not through God, that is either admiration, or pity. However, when the soul, through God loves the soul, without consideration for the appearance of the body - beauty or ugliness - that is love. That is true love. For in love is life.
I consider those fallen mourners more blessed than those who have not fallen and are not mourning over themselves; because as a result of their fall, they have risen by a sure resurrection.
Mourning according to God is sadness of soul and the disposition of a sorrowing heart, which ever madly seeks that for which it thirsts; and when it fails in its quest, it painfully pursues it, and follows in its wake grievously lamenting. Or thus: mourning is a golden spur in a soul which is stripped of all attachment and of all ties, fixed in a soul which is stripped of all attachment and of all ties, fixed by holy sorrow to watch over the heart.
