Ascetic Discipline
The defining feature of Dorotheus's life in the sources is the severity of his physical regimen. By day, in the noonday heat, he went out to gather stones in the desert near the sea and used them to build cells; the synaxarion presents this labor as service to other hermits, and Palladius adds that the elder completed roughly one cell a year, then vacated it for those unable to build their own. By night he occupied himself with handwork, weaving ropes or baskets of palm leaves, by which he earned the few supplies he needed.
His diet, as Palladius records it, was six ounces of bread and a bunch of herbs with water in proportion, taken once a day. He was especially noted for refusing sleep: he did not lie down to rest, but only dozed off involuntarily while working or eating. When Palladius, troubled by the harshness of this discipline, urged the old man to spare his body, Dorotheus is said to have answered, 'If you can persuade angels to sleep, you will also persuade the zealous man.'
