Do you recall how, when you went to school, you had occasionally to review the lessons of the preceding weeks or months? That custom is based on a sound principle. I am now having my review lessons. By and by, before I return to the world, I shall review these reviews, fixing by will the memories which I specially wish to carry over with me. It would be practically impossible to carry over intact the great panorama of experience which now unrolls itself before the eyes of my memory; but there are several fundamental things, philosophical principles and illustrations, which I must not forget. Also I want to take with me the knowledge of certain formulæ and the habit of certain practices which you would probably call occult; by means of which, when I am mature again in my new body, I can call into memory this very pageant of experience which now rolls before me whenever I will it. No, I am not going to tell you about your own past. You must, and can, recover it for yourself. So can anyone who knows the difference between memory and imagination. Yes, the difference is subtle, but as real as the difference between yesterday and to-morrow. I do not want you to be in any hurry about coming out here to stay. Remain where you are just as long as possible. Much that we do on this side you can do almost as well while still in the body. Of course you have to use more energy, but that is what energy is for--to use. Even when we store it, we store it for future use. Do not forget that. One reason why I rest much now and dream and amuse myself is because I want to store as much energy as possible, to come back with power. It is well that you have taken my advice to idle a little and to get acquainted with your own soul. There are surprises in store for the person who will deliberately set out on the quest of his soul. The soul is not a will-o’-the-wisp; it is a beacon light to steer by and avoid the rocks of materialism and forgetfulness. I have had much joy in going back over my Greek incarnations. What concentration they had--those Greeks! They knew much. The waters of Lethe, for instance,--what a conception!--brought from this side by masterly memory. If man would even try to remember, if he would only take time to consider all that he has been, there would be more hope of what he may become! Why, do you know that man may become a god--or that which, compared with ordinary humanity, has all the magnitude and grandeur of a god? “Ye are gods,” was not said in a merely figurative sense. I have met the Master from Galilee, and have held communion with Him. There was a man--and a god! The world has need of Him now. LETTER XXVII THE MAGIC RING IT would be hard for you to understand, merely by my telling you, the difference between your life and ours. Begin with the difference in substance, not only the substance of our bodies, but the substance of natural objects which surround us.
