It is necessary that we live in Christ, the Word of God and become Christ and the Word of God by grace. This is achieved when we live in the Church and participate in its holy mysteries...[and also] with the invocation of the name of Jesus and the reciting of the Jesus prayer. "Lord Jesus Christ, Son of God, have mercy on me, a sinner", especially as the Jesus prayer is very closely associated with Holy Communion. All of the theology of our holy Orthodox Church is hidden in this small prayer. That is why we would always meditate on the sweetest and most joy-producing name of Jesus. The Jesus prayer is not only for monks. Of course, they have the opportunity to live continually within it. However, we, who are sinners, can also recite it. Let us set aside a certain time for this purpose and begin by saying the prayer for ten minutes in the morning and ten minutes at night, as undistractedly as possible. It is very important to set aside a fixed time (even if a very short one) where there are no interruptions. With the passage of time this certain hour will become longer and will sweeten the soul, the lips... Let us say it even when we walk in the street as well as before falling asleep, whenever we have spare time. Let husband and wife or all the family say it in the morning and in the evening for a few minutes. One of them should recite it calmly and peacefully and the rest of them Listen to it. Much grace will come then to the family. There are many couples and families that have practised it and have seen miracles in their lives... Those who want to go deeper in prayer need an experienced spiritual guide.
