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.
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.
Sleep is a particular state of nature, an image of death, inactivity of the senses. Sleep is one, but, like desire, its sources and occasions are many; that is to say, it comes from nature, from food, from demons, or perhaps, sometimes, from extreme and prolonged fasting, through which the flesh is weakened and at last longs for the consolation of sleep.
St. John Climacus was asked if there are reliable signs by which it's possible to know whether a soul is drawing near to God or moving away from Him. After all, regarding ordinary things there are clear signs as to whether they're good or not. When, for instance, cabbage, meat or fish begins to rot, it's easy to notice it, since the rotting object begins to give off a foul odor, the color and taste change, and its external appearance witnesses to its deterioration. Well, and what about the soul? After all, it's bodiless and can't give off a bad smell or change its appearance. To this question the Holy Father replies, 'A sure sign of the deadening of the soul is the avoidance of church services.'
A characteristic of those who are still progressing in blessed mourning is temperance and silence of the lips; and of those who have made progress – freedom from anger and patient endurance of injuries; and of the perfect – humility, thirst for dishonors, voluntary craving for involuntary afflictions, non- condemnation of sinners, compassion even beyond one’s strength. The first are acceptable, the second laudable; but blessed are those who hunger for hardship and thirst for dishonor, for they shall be filled with the food whereof there can be no satiety.
As long as the flesh is in full health, let us observe abstinence at all times and in every place. When it has been tamed (which I do not suppose is possible this side of the grave), then let us hide our accomplishment.
If it is a mark of extreme meekness, even in the presence of one’s offender, to be peacefully and lovingly disposed towards him in one’s heart, then it is certainly a mark of hot temper when a person continues to quarrel and rage against his offender, both by words and gestures, even when by himself.
Let your very dress urge you to the work of mourning, because all who lament the dead are dressed in black. If you do not mourn, mourn for this cause. And if you mourn, lament still more that, by your sins, you have brought yourself down from a state free of labors to one of labor.
Just as over-drinking is a matter of habit, so too from habit comes over-sleeping. Therefore we must struggle with the question of sleep, especially in the early days of obedience, because a long-standing habit is difficult to cure.
