Selections from The Arena, On Prayer: by St. Ignaty (Brianchaninov)
The Power of the Jesus Prayer. Based on the Testimony of the Nun Tatiana (1912). "If someone dies while saying the Jesus Prayer, his soul stands in the presence of the Lord, and he will be inseparable from Him for eternity. Likewise, if a man dies while uttering the prayer, 'Most Holy Theotokos, save me, a sinner,' then he will be inseparable from the Mother of God. If someone is not able to utter even a single word, then, if he struggled to attain this prayer during his life on earth, his soul will say it for him on his deathbed. The state in which the soul leaves the body is the state in which it abides forever. There will be no change for the better. Only if one is commemorated (on earth) can he alter the state of his soul."
