BOOK IX. OF THE SPIRIT OF DEJECTION.
CHAPTER IV: Whence and in what way dejection arises. 

“BUT Sometimes it is found to result from the fault of previous anger, or to spring from the desire of some gain which has not been realized, when a man has found that he has failed in his hope of securing those things which he had planned. But sometimes without any apparent reason for our being driven to fall into this misfortune, we are by the instigation of our crafty enemy suddenly depressed with so great a gloom that we cannot receive with ordinary civility the visits of those who are near and dear to us; and whatever subject of conversation is started by them, we regard it as ill-timed and out of place; and we can give them no civil answer, as the gall of bitterness is in possession of every corner of our heart.”

CHAPTER V: That disturbances are caused in us not by the faults of other people, but by our own. 

“WHENCE it is clearly proved that the pains of disturbances are not always caused in us by other people’s faults, but rather by our own, as we have stored up in ourselves the causes of offence, and the seeds of faults, which, as soon as a shower of temptation waters our soul, at once burst forth into shoots and fruits.”


CHAPTER VII: That we ought not to give up intercourse with our brethren in order to seek after perfection, but should rather constantly cultivate the virtue of patience. 

AND so God, the creator of all things, having regard above everything to the amendment of His own work, and because the roots and causes of our falls are found not in others, but in ourselves, commands that we should not give up intercourse with our brethren, nor avoid those who we think have been hurt by us, or by whom we have been offended, but bids us pacify them, knowing that perfection of heart is not secured by separating from men so much as by the virtue of patience. Which when it is securely held, as it can keep us at peace even with those who hate peace, so, if it has not been acquired, it makes us perpetually differ from those who are perfect and better than we are: for opportunities for disturbance, on account of which we are eager to get away from those with whom we are connected, will not be wanting so long as we are living among men; and therefore we shall not escape altogether, but only change the causes of dejection on account of which we separated from our former friends. 

CHAPTER X: Of the only thing in which dejection is useful to us.
AND so we must see that dejection is only useful to us in one case, when we yield to it either in penitence for sin, or through being inflamed with the desire of perfection, or the contemplation of future blessedness. And of this the blessed Apostle says: “The sorrow which is according to God worketh repentance steadfast unto salvation: but the sorrow of the world worketh death.”

CHAPTER XIII: The means by which we can root out dejection from our hearts.
WE should then be able to expel this most injurious passion from our hearts, so that by spiritual meditation we may keep our mind constantly occupied with hope of the future and contemplation of the promised blessedness. For in this way we shall be able to get the better of all those sorts of dejection, whether those which flow from previous anger or those which come to us from disappointment of gain, or from some loss, or those which spring from a wrong done to us, or those which arise from an unreasonable disturbance of mind, or those which bring on us a deadly despair, if, ever joyful with an insight into things eternal and future, and continuing immovable, we are not depressed by present accidents, or over-elated by prosperity, but look on each condition as uncertain and likely soon to pass away.

Of the eight principal spirits or faults, dejection and acedia most effectively link the monastic world with today’s psychological suffering. The spirit or demon of dejection is described as one that attacks at random, and prevents the monk from having gladness of heart.[32] It makes the monk impatient and rough with the brethren and causes him to feel angry, crushing and overwhelming him with despair.[33] Cassian also locates the origin of dejection as being from “previous anger” or a previous “lack of gain that has not been realized.”[34] The monk isolates himself and no longer desires to engage in discourse with others, so that Cassian labels dejection the “gall of bitterness that is in possession of every corner of their heart.”[35] Interestingly, Cassian discusses how this demonic spirit is not necessarily a result of the actions of others, but actions of the self. Cassian elaborates that one in this state should not isolate himself, but rather continue to interact with his fellow monastic brethren. This in itself is a remedy against this spirit.[36] 

However, Cassian goes on to discuss that some dejection is acceptable and therapeutic. This is the sorrow that leads an individual to penitence for sin.[39] Finally, he ends the relevant chapter by noting that the way to terminate devilish dejection is spiritual meditation, and keeping the mind occupied with the hope of the future. In examining this chapter of Cassian’s work, clear symptoms emerge, as well as treatment modalities for what is considered depression in the modern world.

In Book X of the Institutes, Cassian begins to describe accidie, or acedia, known as the “midday demon,”[40] as Evagrius had also done, although in more detail in specific relation to the emotions.[41] While similar to the demon of dejection, acedia consists of the added features of apathy, sluggishness, sloth, and irritability. In naming acedia the “midday demon,” Cassian posits that these demonic attacks often occur around the sixth hour and seize the monk. Carelessness and anxiousness are the main components of acedia, as well as frequent complaining.[42] The monk looks anxiously and often sighs at his other brethren. There are also moments where he is idle and useless for spiritual work. Cassian notes that sometimes the midday demon can manifest in different forms: sometimes one may isolate more, and in other times one may become a busy-body and seek consolation from others — an action which Cassian describes as entanglement in secular business.[43] 

Cassian similarly recognized that often, anger and the lack of accomplishing a goal can lead to the demon of dejection. Anger and failure are, after all, often linked to stressful situations in an individual’s life.
