Our enemies (demons) fell because of their pride, and call us to follow them, and bring us feelings of praise. And if your soul accepts that praise, then grace will depart, until the soul becomes humble again. And so all your life you must learn the humility of Christ.
We are told to draw the waters of life from the sources of the Divine Writings which alone can extinguish the passions that plague us and set us on the road to intellectual truth.
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!
In the beginning there are a great many battles and a good deal of suffering for those who are advancing towards God and afterwards, ineffable joy. It is like those who wish to light a fire; at first they are choked by the smoke and cry, and by this means obtain what they seek -- as it is said, 'Our God is a consuming fire' -- so we also must kindle the divine fire in ourselves through tears and hard work.
The heavenly is experienced through the Holy Spirit, and the earthly through the mind: whoever wants to experience God with his mind through learning is in vainglory, for God can only be experienced through the Holy Spirit.
Take care never to receive Communion while you have anything against anyone, even if this is only a hostile thought. Not until you have brought about reconciliation through repentance should you communicate, [receive the Mysteries]. But you will learn this, too, through prayer.
Understand me. It is so simple. People who do not know God, or who go against Him, are to be pitied; the heart sorrows for them and the eye weeps. Both paradise and torment are clearly visible to us: We know this through the Holy Spirit. And did not the Lord Himself say, 'The kingdom of God is within you?' Thus eternal life has its beginning here in this life; and it is here that we sow the seeds of eternal torment.
A man who falls into sin is different from the way he was created. He is different, because he changes by his own actions the way he was meant to be. Man renounces himself when he becomes a different person through repentance. He leaves a corrupted man, which he had become through sin, and becomes such as he once was created, through mercy.
It is not always possible to fulfill the usual rules; one must take circumstances into account and try to fulfill what they make possible, as far as one can. The demons themselves are not unmindful of this law. So, being in constant enmity with us, they prevent us from doing what is possible and urge us to do what is impossible.
As a blacksmith can do nothing without the help of fire, however skilled he may be in wielding his tools, so a man should do everything he can on his side to purify his heart, using virtues as tools for this purpose; but without fire of the Spirit, everything he does will remain inactive and useless for his aim, for by itself what he does is powerless to cleanse the soul of its dirt and foulness.
