"D: Master Samael Aun Weor, we would like to ask you a question globally, on behalf of the whole Gnostic group from Venezuela. Please could you tell us something about our past existences?
M: Well, I am going to tell you a great truth. If you observe carefully the different pseudo-esoteric and pseudo-occultist schools that exist in the world, you will see that these questions are much in abundance. A medium will tell you that you are the reincarnation of Napoleon Bonapart, or some reincarnation of one of the twelve apostles; another one will tell you he has been Count so and so, or Marie Antoinette. I know more than half a dozen of such "reincarnated Marie Antoinettes" about. So, in conclusion, they all are grand, and none small...
Telling people their past lives is of no use. In practice I have realised that it is absurd. Really, what is useful is that each person may remember his past existences, and one has to start with the previous one.
Lie down comfortably on your beds, having your arms well relaxed, your legs well relaxed, your body loose, relaxed, and immediately concentrate on the last instant of your previous existence, on its last second. Do this exercise at the time when you feel best disposed to sleep. For mantras, you can use RAOM-GAOM. [pronounced rhah-Ohm, ghah-Ohm]
Nevertheless, as I say, this exercise needs to be done in those moments when you feel most disposed to sleep. The concentration has to be deep on the last instant of your previous existence. Your physical body could fall asleep in that moment, but you will in that moment manage to see yourselves on your death beds, surrounded by your relatives; you will hear again the words they spoke to you, etc, etc, etc. You will have then got to remember the last instant of your previous existence.
Some other day, you can do the same exercise in order to remember the last instant but one. You will be able to see the penultimate instant, and like this you can go backwards with each exercise, trying to remember your previous existence. You will gradually live the memories of your previous existence like frames, scenes, events, until your recall of it all is completed.
Once the recall of your previous existence as a whole has been completed backwards, from old age, to maturity, to youth, to childhood and birth, you will then be able to continue with your penultimate existence, then the antepenultimate, and like this you can successively recall your existences going backwards, until you remember them all. RAOM-GAOM are the mantras.
This is something worthwhile: to remember by oneself, making oneself conscious of one's previous existences, and not having somebody else telling you. I do not want to imitate the example of those schools of the cheap pseudo-esotericism and pseudo-occultism. I want each person to live this consciously, to remember their previous existences themselves... " pp. 2475-2476
