Prayer offered up at night possesses a great power, more so than the prayer of the day-time. Therefore all the righteous prayed during the night, while combating the heaviness of the body and the sweetness of sleep and repelling bodily nature.
We should not miss any chance to us to say the Jesus Prayer. We must not let our mind wander in vain things. In saying the Jesus Prayer one's mind finds rest and joy. It is like small children who for the whole day run around, shouting and playing and hitting each other. But the one thing that gives them rest and great joy is when at night they find themselves in their mother's arms. This way also one's mind instead of being scattered about, out to be devoted to mental prayer.
As it is not possible to cross over the great ocean without a ship, so no one can attain to love without fear. This filthy sea, which lies between us and the paradise of the heart, we may cross by the boat of repentance, whose oarsmen are those of fear. But if fear's oarsmen do not pilot the boat of repentance whereby we cross over the sea of this world to God, we shall be drowned in the sordid abyss.
Whenever in your path you find unchanging peace, beware: you are very far from the divine paths trodden by the weary feet of the saints. For as long as you are journeying in the way to the city of the Kingdom and are drawing near the city of God, this will be a sign for you: the strength of the temptations that you encounter. And the nearer you draw close and progress, the more temptations will multiply against you.

Before the war begins, seek out your ally; before you fall ill, seek out your physician; and before grievous things come upon you, pray, and in the time of your tribulations you will find Him, and He will listen to you.
What salt is for any food, humility is for every virtue. To acquire it, a man must always think of himself with contrition, self-belittlement and painful salf-judgment. But if we acquire it, it will make us sons of God.
So long as the soul is sick with passions, its senses have no perception of the spiritual; and the soul does not even know how to desire it, but desires it only from hearsay and writings. The power of the soul is cured of these diseases by the hidden practice of commandments, with sharing in Christ's passion.
Stillness mortifies the outward senses and resurrects the inward movements, whereas agitation does the opposite, that is, it resurrects the outward senses and deadens the inward movements.
It is as necessary for a man to say the Jesus Prayer as it is for a ship in danger to send out steadily the S.O.S. signal: Lord Jesus Christ have mercy on me.
Just as we must beware of overeating, so too we must beware of excessive temperance or abstinence. Excessive temperance weakens the body, destroys wakefulness, coolness and freshness which are indispensable for vigilance, and which fade and weaken when the physical powers succumb and fail. If you force a weak body to labor beyond its powers, you subject your soul to double darkness, and lead it into confusion (and not relief)...
