In these lessons we have tried to give you the Key to the Mysteries, but unless you have studied the other lessons in which the Occult Teachings have been set forth, you will not be able to see their application in Mystic Christianity. You must bring Knowledge to these lessons, in order to take away knowledge. THE ELEVENTH LESSON THE ANCIENT WISDOM. The doctrine of Metempsychosis or Re-incarnation has its roots deeply imbedded in the soil of all religions--that is, in the Inner Teachings or Esoteric phase of all religious systems. And this is true of the Inner Teachings of the Christian Church as well as of the other systems. The Christian Mysteries comprised this as well as the other fundamental occult doctrines, and the Early Church held such teachings in its Inner Circle. And, in its essence, the doctrine of Re-birth is the only one that is in full accord with the Christian conception of ultimate justice and "fairness." As a well known writer has said concerning this subject: "It relieves us of many and great difficulties. It is impossible for any one who looks around him and sees the sorrow and suffering in the world, and the horrible inequality in the lives of men--not inequality in wealth merely, but inequality in opportunity of progress--to harmonize these facts with the love and justice of God, unless he is willing to accept this theory that this one life is not all, but that it is only a day in the real life of the soul, and that each soul therefore has made its place for itself, and is receiving just such training as is best for its evolution. Surely the only theory which enables a man rationally to believe in Divine justice, without shutting his eyes to obvious facts, is a theory worthy of study.
