The beam of blue light down the canal!
Once upon a time, not that long ago, I visualized the energy of someone meditating on the idea of time. What I saw captivated me, humbling my breath to a silent standstill in awe of the wonder. The sensation and visualization of that experience entered my waking unconscious in a lucid dream, that I drew and wrote about at lengths upon waking. I must have written 3 or 4 poems circumscribing to the best of my ability what that experience was. The heart of the matter was a ribbed tunnel, a round blue sound, a beam of peace, neon, blue and infinite.
I read the linked article above and I cannot help but consider the connection between the blue light beam canal and what came to me during a visualization.
