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.
The key to Divine gifts is given to the heart by love of neighbor, and, in proportion to the heart's freedom from the bonds of the flesh, the door of knowledge begins to open before it.
It is impossible for the soul to be liberated from turbulent thoughts without the virtue of non-possessiveness. And without peace of the bodily senses it is impossible for the soul to have a peaceful intellect. And if it does not come into temptations it will not acquire wisdom of the Holy Spirit. And without laborious and persistence in reading, it will not come to the discernment of thoughts. And without the stillness of thoughts, the intellect cannot move to seek the hidden mysteries of God.
Do not be surprised that when you draw near to virtue, grievous and intense tribulations come to you on all sides: for virtue is not considered virtue, if it does not involve hard work.
A life of spiritual endeavor is the mother of sanctity; from it is born the first experience of perception of the mysteries of Christ--which is called the first stage of spiritual knowledge.
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.
Trial is profitable for every man... Ascetic strugglers are tried, that they may add to their riches; the slothful are tried, that they may thereby guard themselves from what is harmful to them; the sleepy are tried, that they may be armed with wakefulness; those who are far away are tried, that they may draw nearer to God; those who are God's own are tried, that with boldness they may enter into His house. The son who is not trained will receive no profit from the riches of his father's house. For this reason, then, God first tries and afflicts, and thereafter reveals His gift. Glory be to our Master Jesus Christ Who brings us the sweetness of health by stringent medicines!
Let us love silence till the world is made to die in our hearts. Let us always remember death, and in this thought draw near to God in our heart--and the pleasures of this world will have our scorn.
Ever let mercy outweigh all else in you. Let our compassion be a mirror where we may see in ourselves that likeness and that true image which belong to the Divine nature and Divine essence. A heart hard and unmerciful will never be pure.
