Ascetic Struggle
John's life is centered on his ascetic warfare against the passion of lust. His most famous feat, related in the synaxarion, was carried out in a pit he dug for himself: with the onset of Great Lent he climbed into it and covered himself with earth up to the shoulders, remaining so through the whole of the Lenten season.
By long endurance, the tradition holds, he was at last delivered from the passion that had afflicted him since youth, and is said to have received the assurance that the temptation had been permitted so that he might be purified like gold.
