Called to be a monastic by an audible voice at his baptism, Saint Nicodemus held off taking up the veil to be in obedience to his parents who shared a well-intentioned concern for his well being. After their death, he forgot his earlier intention and became blacksmith in Moscow. But when he was delivered from the effects of a pernicious poison by the intercessions of Saint Basil the Fool for Christ, he remembered his calling, sold all his possessions, and became a monk. Always longing for a deeper hesychia, the Saint joined a community in the far north of the country that was overseen by Saint Serapion. After a few years, he received a blessing to become a hermit and settled along the Kozhyug River. There he submerged himself in a life of extreme asceticism, fasting to his absolute limit and standing in prayer for long hours without being aware of the passage of time. He was granted the gift of compunction and the constant stream of tears carved deep furrows in his face. Furious by his display and threatened by the grace that God visited on him as a result, the demons hurled themselves at Nicodemus hoping to intimidate him, cause him to despair, and drive him off. But the Saint treated them with disdain and casually drove them away by his prayer. Utterly defeated, the demons thought they would try to turn this to their advantage, tempting him to pride by withdrawing their attacks for a time. Their hope was that their absence would cause him to glory in his ability to banish them. So, when they thought he least expected it, they threw themselves against him again with all their might, but found the Saint as immoveable as before, grounded as he was in humility and watchfulness. As a result, Saint Nicodemus lived out the rest of his days in peace.
