What we as humans call memory is actually that part of the information stored in our subconscious that we can realize in our day consciousness.
So memory loss does not mean that the memory is gone, but that there is a disorder in brain or nerves, which blocks the day consciousness from retrieving the information.

-And there are possibilities that a human being loses his memory because of a shock and because of a fall and no longer lives in the existing day consciousness. So that shock has brought off something by means of which his life of feeling is disengaged. That is not the loss of memory, but a disturbance has entered the normal, natural, spiritual thinking which comes from the centre of feeling, the solar plexus, that goes through the body over the back and comes back again, goes through the brain and suddenly that cannot go any further because there something is broken, brought out of balance. Do you feel it? And then the human being can no longer think and then they say: ‘Yes, I do not know anymore.’ They can talk, because that is still there. Thinking, yes, no… And now there is also something crazy, something strange, and the doctors experienced that, they said… ‘Yes’, someone says, ‘then I started to talk about the cows which I had, and I was there and there and there, in my neighbourhood: yes, but I no longer live here, I no longer live here.’ Then those people said: ‘You see, the memory has gone.’ Then the human being stood definitely, and suddenly, because of a shock, because of that shock, in the rein- carnation, the previous life. And they did not understand anything about that. Happened more than once. Is it clear?
-Now I can continue of course to also follow those phenomena, but that is already no longer necessary because this is the core. So because of the shock you can really lose your memory, that is the day conscious feeling and thinking, because you, because you do not… there is a little spring in that machine, a little cogwheel is broken, and now you cannot think, so you are standing somewhere. Where are you standing? In your previous life and nowhere else. He says: ‘Yes, I am there, I have learned to talk, that is still there, you can still think.’ He says: ‘The thinking continues.’ Yes, but now that thinking no longer goes through the brain, through that source, but now it goes out directly from the life of feeling, and at that moment the academic, the doctor could have said: ‘My God, my God, that human being is thinking without brains.’ It quickly looks for a channel and continues.
