Life and Asceticism
Palladius reports that Dorotheus ate daily six ounces of bread with a bunch of herbs and drank water in proportion. He never lay down to sleep on a mat or a bed, but would sit up through the night at his work, dozing only occasionally while working or after eating. When Palladius questioned the severity of this discipline, Dorotheus is said to have answered of his body, 'It kills me, I kill it.'
A frequently repeated account concerns the well from which the hermits drew water. When his disciple reported that a serpent had fallen into it and poisoned the water, Dorotheus went to the well himself, made the Sign of the Cross over the water, drank, and declared that where the Cross is present the demonic powers can do no harm.
