Carl Jung: The mandala as depicting “a kind of central point within the psyche.”
The mandala’s basic motif is the premonition of a center of personality, a kind of central point within the psyche, to which everything is related, by which everything is arranged, and which is itself a source of energy….
This center is not felt or thought of as the ego, but if one may so express it, as the self. Although the center is represented as the innermost point, it is surrounded by a periphery containing everything that belongs to the self — the paired opposites that make up the total personality.
This totality comprises consciousness first of all, then the personal unconscious, and finally an indefinitely large segment of the collective unconscious whose archetypes are common to all mankind.”
