Vigilance at last night-hours and getting up at night is the most important stipulations of the mystical traveler. And to attain the sightly purpose is impossible except with night-watching (vigil).Some of Gnostic have emphasized on rising at night, three hours before the Morning Athan in winter and an hour and a half in summer.For wakefulness at last night-hours (dawn) could get help from sleep early at night and eating little before sleeping and reading the last verse (Ayah) of sorah Kahf.
