While on Lindisfarne, Cuthbert used to pray day and night. Sometimes he prayed in solitude on Hobthrush Isle (also known as St. Cuthbert's Island -- my note). At other times he used to work with his hands so he could stay awake to pray. He also walked all around the island to see how everything was getting on. As he walked he sang psalms. He slept little, sometimes going all day without sleep. Even when he was sleeping if he was unexpectedly awakened he was never angry. He used to say, "No one who awakens me angers me. He who wakes me up makes me happy for driving away the heaviness of sleep and making me think of something useful." When Cuthbert celebrated Mass he could not do it without shedding tears. When he sang he sang from a full heart. The music often broken by the sound of his sighs. He was upright and holy in his personal life. He reproved wrongdoing in others but was most kind and gracious with the penitent. He was even known during confession to break into tears, thus by his example prompting greater penitence and more complete forgiveness.
As time went on Cuthbert had a greater desire to be alone with God. He withdrew more and more to spend time on Hobthrush Isle....
