The Heart (An Orthodox Christian Spiritual Guide)
"Every man has two hearts. One is the body's heart. The other is the soul's heart. The good or bad condition of both of our hearts is very important. If something happens to either one, then we have heart problems and our life is in danger, whether it is the life of our body or the life of our soul. Unfortunately, many Christians, both clergy and laity still do not understand this. And although they take great care to appear externally good, decent, honest, consistent , religious and loyal people, unfortunately they care very little, if at all, or almost at all, about having a clean, good and holy heart. This, however, is a mistake. For the Orthodox faith, the only thing that is prominent and to which it is necessary to place our greatest interest, is in the heart's condition. "
