A soul is that which observes itself and other phenomenon thus exists through a self referential loop and loop between itself and other beings. A soul is a loop.
A loop is that which repeats thus to observe is the manifest repetition through the repeating images (ie memory), thus the soul is memory. This memory is a loop.
The inversion of one image to another, as the change of images in observation, is thought, thus the soul is thought. This thought as inversion, or change, is the turning of one image to another therefore a loop as well.
The soul is thought and memory and as such is 2 loops. The loops repeat and turn into eachother thus result in a third loop. The soul is a triad of loops.
