Ascetic Life
By the surviving tradition, John lived alone in a cave in the wilderness near Jerusalem, sustaining a regimen of fasting and continual prayer. His sole possession was an icon of the Theotokos, before which he maintained a burning lampada, a detail the synaxarion preserves as an emblem of his complete renunciation of material goods.
The same tradition relates that when a visiting monk questioned his stark and possessionless manner of living, the Elder replied that his cave held spiritual riches greater than any earthly treasure, a saying recorded as the expression of his ascetic outlook.
