The treatment ordered by wise physicians of the past, and by those that follow after, is not one and the same, rather doth it depend on what aileth the patient; and although the remedy may change, the aim is always to bring the patient back to health. In the dispensations gone before, the feeble body of the world could not withstand a rigorous or powerful cure. For this reason did Christ say: ‘I have yet many things to say unto you, matters needing to be told, but ye cannot bear to hear them now. Howbeit when that Comforting Spirit, Whom the Father will send, shall come, He will make plain unto you the truth.’ [1]

Therefore, in this age of splendours, teachings once limited to the few are made available to all, that the mercy of the Lord may embrace both east and west, that the oneness of the world of humanity may appear in its full beauty, and that the dazzling rays of reality may flood the realm of the mind with light.
