Deep Space
When you go deep enough into the unconscious within your body you eventually enter the reality of what we call outer space, or the space between the stars - astral space (from the Latin ‘astrum’ - star). This is another world of supreme stillness and nothingness. Conversely, if man is ever able to actually travel deep enough into outer space, far beyond the influence of the solar system, he will end up in his unconscious - the same other world of sublime stillness and nothingness. But unless he has been spiritually prepared, which is most unlikely, he won’t perceive any great difference and will fill this space as he fills his inner space - with the mundanity of his thinking and rationality. For 'out there’ and 'in here’ merge to become the one consciousness. But ultimately even 'out there’ vanishes to become 'in here.'
