"...Let us come back to the Paracelsan process of transforming the Iliaster. Paracelsus calls this proccess a retoria disillatio. The purpose of distillation in alchemy was to extract the volatile substance, or spirit, from the impure body. This process was a psychic as well as a physical experience. The retoria distillatio is not a known technical term, but presumably it meant a distillation that was in some way turned back upon itself. It might have taken place in the vessel called the Pelican where the distillate runs back into the belly of the retort. This was the "circulatory distillation," much favoured by the alchemists. By means of the "thousandfold distillation" they hoped to achieve a particularly "refined" result. It is not unlikely that Paracelsus had something like this in mind, for his aim was to purify the human body to such a degree that it would finally unite with the maior homo, the inner spiritual man, and partake of his longevity. As we have remarked, this was not an ordinary chemical operation, it was essentially a psychological procedure. The fire to be used was a symbolical fire, and the distillation had to start "from the midst of the centre" (ex medio centri). Jung, Carl. Alchemical Studies, Collected Works of C.G. Jung, Volume 19.

Ex Medio Centri: Another alchemical example of dreaming. Here I come home to find my house burned down. A house of many rooms existing alone on a knoll. The basement is still in tact and I know that I will have to live in it for a while. This is a clear metaphor for having to live in the unconscious while my ego and consciousness are remade. This dream absolutely coincided with a personal breakthrough I had at the time. Albeit a scary one, the results ended up being very fulfilling.
