"Have you remembered that, in my transcendent state, as I looked at the rocks, sand, mountains, water below me in the Dead Sea, all appeared to be as a 'shimmer of motes'? Rock, sand, mountains, water were differentiated one from the other, only by the difference in the intensity of the 'shimmer of motes' and by the apparent density of motes within the shimmer.
There is no other way I can describe what I saw when on earth or convey the facts concerning the true substance of 'matter' and the apparently solid fabric and construction of your world.
In modern speech, you would probably call the 'shimmer of motes', a vibration of particles.
Perhaps you could combine the two terms and describe the most fundamental visible 'reality', as a 'shimmer of particles'. This conveys the sense of the 'light glow' in which I saw the particles dance." [Christ Returns - Speaks His Truth, Letter 3, page 4]
