Ascetic Life
From childhood Luke is reported to have practiced strict abstinence, keeping a sparing diet and a total fast on Wednesdays and Fridays. At about the age of fourteen he withdrew to a mountain known as Ioannou (Ioannitza), where by tradition he lived as an ascetic for about seven years. He received the small monastic habit and, over the course of his life, lived at several locations, including a period of about ten years in association with a stylite.
Luke is remembered as one of the earliest saints described as levitating during prayer; his mother is said to have witnessed him lifted above the ground while praying as a child. After repeated withdrawals to solitude he settled around 946 near Stiris, where his reputation for holiness drew others and a small monastery formed around him.
