Four Elements page 3
There is a direct parallel between the way the Mind transforms beingness
(physical reality) into nonbeing
(thought) and the way that Fire takes solid wood and sends it into the Air as smoke and ash.
The Mind is the element of Fire as it manifests as an aspect of our beings. The Mind is a transitioning component between the opposites, between our Bodies and our Spirits, transforming the physical reality experienced by the Body into thoughts and ideas.
In this way our Mind fuels itself with the physical world and transforms it into Consciousness/Air. In this way we integrate the two opposite halves of the Universe.
