For [French mystical philosopher, Henry] Corbin, the Otherworld is a pre-condition of our own world, meaning that our world would not exist without it. The Otherworld thus encompasses our reality rather than being situated by it. He explains this difficult concept by using the following analogy. Although we commonly consider our spirit to be situated within our body or brain during its incarnation, an assumption forced upon us by Descartes’ separation of the mind from the body (and the natural world), the converse is actually true. The body is encompassed by the spirit. Furthermore, imagination, which has the ability to connect with and move between the two worlds, encompasses our psychological and cognitive functions. We are therefore embraced and held by a world of magic which appears to us in visions, dreams and symbols yet it is a world to which we have become increasingly blind and mute.
