We should shun loose speech like an asp’s venom and too much company like a ‘progeny of vipers’ (Matt. 3:7), for it can plunge us into total forgetfulness of the inner struggle and bring the soul down from the heights of the joy that purity of heart gives us. This accursed forgetfulness is as opposed to attentiveness as water to fire, and forcibly fights against it all the time. Forgetfulness leads to negligence, and negligence to indifference, laziness and unnatural desire. In this way we return to where we started, like a dog to his own vomit (cf 2 Pet. 2:22). So let us shun loose speech like deadly poison. As for forgetfulness and all its consequences, they can be cured by the most strict guarding of the intellect and by the constant invocation of our Lord Jesus Christ. For without Him, we can do nothing (cf. John 15:5).  –St Hesychius from the Philokalia

In one who is attempting to dam up the source of evil thoughts and actions, continuity of watchful attention in the intellect produced by fear of hell and fear of God, is not hindered by God’s withdrawals from the soul, and by the advent of trials which chasten and instruct. For these withdrawals and unexpected trials help us to correct our life, especially when, having once experienced the tranquility of watchfulness, we neglect it. Continuity of attention produces inner stability; inner stability produces a natural intensification of watchfulness; and this intensification gradually and in due measure gives contemplative insight into spiritual warfare. This in its turn is succeeded by persistence in the Jesus Prayer and by the state that Jesus confers in which the intellect, free from all images, enjoys complete quietude.  –St Hesychios ‘Philokalia’

Our seventh struggle is against the demon of self-esteem, a multiform and subtle passion which is not readily perceived even by the person whom it tempts. The provocations of the other passions are more apparent and it is therefore somewhat easier to do battle with them, for the soul recognizes its enemy and can repulse him at once by rebutting him and by prayer. The vice of self-esteem, however, is difficult to fight against, because it has many forms and appears in all our activities—in our way of speaking, in what we say and in our silences, at work, in vigils and fasts, in prayer and reading, in stillness and long-suffering. Through all these it seeks to strike down the soldier of Christ. When it cannot seduce a man with extravagant clothes, it tries to tempt him by means of shabby ones. When it cannot flatter him with honor, it inflates him by causing him to endure what seems to be dishonor. When it cannot persuade him to feel proud of his display of eloquence, it entices him through silence into thinking he has achieved stillness. When it cannot puff him up with the thought of luxurious table, it lures him into fasting for the sake of praise. –St John Cassian ‘Philokalia’

A man can be harmed by another only through the causes of the passions which lie within himself. It is for this reason that God, the Creator of all and the Doctor of men’s souls, who alone has accurate knowledge of the soul’s wounds, does not tell us to forsake the company of men: He tells us to root out the causes of evil within us and to recognize that the soul’s health is achieved not by a man’s separating himself from his fellows, but by his living the ascetic life in the company of holy men. When we abandon our brothers for some apparently good reason, we do not eradicate the motives for dejection but merely exchange them, since the sickness which lies hidden within us will show itself again in other circumstances.

Thus it is clear that our whole fight is against the passions within. Once these have been extirpated from our heart by the grace and help of God, we will readily be able to live not simply with other men, but even with wild beasts… –St John Cassian ‘Philokalia’

…If therefore we are to follow the divine laws, we must struggle with all our strength against the demon of anger and against the sickness which lies hidden within us. When we are angry with others we should not seek solitude on the grounds that there, at least, no one will provoke us to anger, and that in solitude the virtue of long-suffering can easily be acquired. Our desire to leave our brethren is because of pride, and because we do not wish to blame ourselves and ascribe to our own laxity the cause of our unruliness. So long as we assign the causes for our weakness to others, we cannot attain perfection in long-suffering.

Self-reform and peace are not achieved through the patience which others show us, but through our own long-suffering towards our neighbor. When we try to escape the struggle for long-suffering by retreating into solitude, those unhealed passions…are merely hidden, not erased: for unless our passions are first purged, solitude and withdrawal from the world not only foster them but also keep them concealed, no longer allowing us to perceive what passion it is that enslaves us. On the contrary, they impose on us an illusion of virtue and persuade us to believe that we have achieved long-suffering and humility, because there is no one present to provoke and test us.

But as soon as something happens which does arouse and challenge us, our hidden and previously unnoticed passions immediately break out like uncontrolled horses that have long been kept unexercised and idle, dragging their driver all the more violently and wildly to destruction. Our passions grow fiercer when left idle through lack of contact with other people. Even that shadow of patience and long-suffering which we thought we possessed while we mixed with our brethren is lost in our isolation through not being exercised. Poisonous creatures that live quietly in their lairs in the desert display their fury only when they detect someone approaching, and likewise passion-filled men, who live quietly not because of their virtuous disposition but because of their solitude, spit forth their venom whenever someone approaches and provokes them. This is why those seeking perfect gentleness must make every effort to avoid anger not only towards men, but also towards animals and even inanimate objects. –St John Cassian ‘Philokalia’

In the whole range of evil thoughts, none is richer in resources than self-esteem; for it is to be found almost everywhere, and like some cunning traitor in a city it opens the gates to all the demons. So it greatly debases the intellect of the solitary, filling it with many words and notions, and polluting the prayers through which he is trying to heal all the wounds of his soul. All the other demons, when defeated, combine to increase the strength of this evil thought: and through the gateway of self-esteem they all gain entry to the soul, thus making a man’s last state worse than his first (Matt 12:45). Self-esteem gives rise to pride, which cast down from heaven to earth the highest of the angels, the seal of God’s likeness and the crown of all beauty. So turn quickly away from pride and do not dally with it, in case you surrender your life to others and your substance to the merciless (cf. Prov. 5:9) demon is driven away by intense prayer and by not doing or saying anything that contributes to the sense of your own importance.

When the intellect of the solitary attains some small degree of dispassion, it mounts the horse of self-esteem and immediately rides off into cities, taking its fill of lavish praise accorded to its repute. But by God’s providence the spirit of unchastity now confronts it and shuts it up in a sty of dissipation. This is to teach it to stay in bed until it is completely recovered and not to act like disobedient patients who, before they are fully cured of their disease, start taking walks and baths and so fall sick again. Let us sit still and keep our attention fixed within ourselves, so that we advance in holiness and resist vice more strongly. Awakened in this way to spiritual knowledge, we shall acquire contemplative insight into many things; and ascending still higher, we shall receive a clearer vision of the light of our Savior. –Philokalia.
