Do everything simply and meekly. Do nothing with an ulterior motive. Don't say, I'll do this in order to have that result, but do it naturally, without taking cognizance of it. That is, pray simply and don't think about what God will bestow on your soul. Don't make any calculations. You know, of course, what God bestows when you enter into communion with Him, but it is as if you don't know. Don't discuss the matter even with yourself. So when you repeat the prayer, "Lord Jesus Christ, have mercy on me”, say it simply and ingenuously and think of nothing other than the prayer. These are very delicate matters and the intervention of the grace of God is required.
