he found himself creating regular, symmetrical images which he later identified as mandalas. He gradually came to realise that these images were nothing less than images of the wholeness of the personality, ‘cryptograms concerning the state of the self which were presented to me anew each day’
Clarke establishes the autobiographical origin of Jung’s mandala theory, tracing it to his own psychological crisis and the discovery that spontaneously produced symmetrical images encode the state of the Self.
