If your heart is truly imbued with Holy Spirit, if your prayer merges your whole heart and soul, then you do not have to say many prayers any longer, but ‘Lord, do not leave me’ or ‘Lord Jesus Christ, Son of God Have mercy on me, a sinner!’, which is the most powerful prayer. Jesus’ name is sweet when summoned, it casts out demons and brings angels back, and makes the heart and mind to be gentle with others. But if are not there, follow the rule of prayer in the prayer book, for calling in prayers the name of God, you call Christ, Virgin Mary, Holy Spirit, Holy Trinity, God the Father, the Saints, all martyrs and your heart receives an inner vibration with all these saints.

Sometimes, I enter this church, and there is no one in it. It is quiet. Entering it I feel that all the Saints are watching me, that they turned their look to me. I feel I am not alone. I feel surrounded by spiritual powers.
