“Up now, slight man! flee, for a little while, thy occupations; hide thyself, for a time, from thy disturbing thoughts. Cast aside, now, thy burdensome cares, and put away thy toilsome business. Yield room for some little time to God; and rest for a little time in him. Enter the inner chamber of thy mind; shut out all thoughts save that of God, and such as can aid thee in seeking him; close thy door and seek him. Speak now, my whole heart! speak now to God saying, I seek thy face; thy face, Lord will I seek. And come thou now, O Lord my God, teach my heart where and how it may seek thee, where and how it may find thee.”
— St. Anselm (1033/35-1109), Archbishop of Canterbury. From his Proslogion. This is what he wrote prior to beginning his theological musings. A good prayer prior to beginning theological musings of any kind!
