Love of God proceeds from conversing with him; this conversation of prayer comes about through stillness, and stillness comes with the stripping away of the self.
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)...
Where there is pride there cannot be grace, and if we lose grace we also lose both love of God and assurance in prayer. The soul is then tormented by evil thoughts and does not understand that she must humble herself and love her enemies, for there is no other way to please God.
As a man whose head is under water cannot inhale pure air, so a man whose thoughts are plunged into the cares of this world cannot absorb the sensations of that new world.
This reversal of thoughts is the strongest means, not only for repelling accidental critical thoughts, but also for completely freeing yourself of this vice…
The Saints in Heaven through the Holy Spirit behold the glory of God and the beauty of the Lord's Countenance. But in this same Holy Spirit they see our lives too, and our deeds. They know our sorrows and hear our burning prayers. When they were living on earth they learned of the love of God from the Holy Spirit: and he who knows love on earth takes it with him into eternal life in the Kingdom of Heaven, where love grows and becomes perfect. And if love makes one unable to forget a brother here, how much more must the Saints remember and pray for us!
It is not possible for any man to draw near to Christ without tribulation, and without afflictions his righteousness cannot be preserved unchanged. If he puts an end to the labors that make righteousness increase, he will put an end to that which guards it, and his righteousness will be like unguarded treasure. And he will be like a gladiator surrounded by enemy ranks and stripped of his weapons, like a ship bereft of its sails and tackle, and like a garden deprived of its source of water.
As it is not possible to walk without feet or fly without wings, so it is impossible to attain the Kingdom of Heaven without the fulfillment of the commandments.
Exercise patience out of love for your fellow man. Exercise patience in order to benefit your soul. For if you do not take your soul into consideration, you lose your patience.
As a man cannot remain unscathed who spares his enemy on the field of battle, so a man engaged in spiritual warfare cannot save his soul if he spares his body.
