The Letters of Elder John Krestiankin.
Servant of God, E.!
What is going on with you is delusion and I have witnessed many such occurrences in my spiritual experience. And if now you are in the very beginning of this pernicious way, the end of this way will be perdition.
Initially the “voice” will teach you to obey him, for his bait will be the word of truth. But when you are completely spiritually paralyzed, the same sweet “voice” will give you a ruinous command, and you, being deluded, will perform it. You must cease to follow the delusion immediately. You should confess and receive the Holy Unction and tell your confessor everything that happens to you.
