Worship must come from a pure heart. Likewise, if purity of heart does not precede the life of solitude, it turns from solitude into introversion, from a means of worship to the goal of fleeing from people, or intolerance of people, or as one of the fathers put it, “Such a person spends a hundred years in his cell, and does not even learn how one should sit.” Therefore, we need to place purity of heart as the primary goal before us. Purity of heart requires you to search yourself, know your mistakes, and work on them.
