Venerable Zachariah the Ascetic of the Kiev Caves

Saint Zachariah the Faster of the Caves was an ascetic in the Far Caves in the thirteenth-fourteenth centuries. He fasted so strictly that he ate nothing baked nor boiled, and he consumed only greens once a day at the setting of the sun. Demons trembled at the mere mention of his name.

Often the monk saw angels, with which he deserved to live in Heaven.
