211. (Also in V.xii.1, V.iv.2, V.iii.1) Abba Daniel affirmed that the blessed Arsenius at vespers on Saturday used to turn his back on the setting sun, and lifting up his hands to heaven persevered in prayer till the rising sun came into view. He would keep vigil on other nights, but near dawn, when the weakness of his human nature demanded that he sleep a little, he would say, “Come on then, you unprofitable servant,” and shutting his eyes would take a little sleep sitting down before getting up again.
When sitting down to work he always had a little basin on his lap to catch the tears which continually flowed from his eyes because of the longing he had for the life eternal.
