Reclusion and Spiritual Deception
Niketas entered the Kiev Caves monastery as a young man and soon wished to become a recluse. The abbot cautioned that such a withdrawal was premature for one so inexperienced, but Niketas would not listen, declaring that he would not be deceived. In his enclosure he encountered what seemed to be signs of grace — a sweet fragrance and a voice joining his prayers — and when he asked to behold God, a demon appeared to him in the form of an angel, to which he bowed down.
Under this influence he abandoned prayer, devoted himself solely to the Old Testament, and began to deliver prophecies to visitors. The elders of the monastery grew suspicious when they observed that he never cited the New Testament, and understood that he had fallen into spiritual delusion. They broke into his cave, drove out the demon through their prayers, and brought him out of seclusion. By the accounts of his life he afterward could not recall the Old Testament he had once memorized and had to learn anew. He wept in repentance and took up the path of humility and obedience.
