The authors propose a vision of the process of individuation, as proposed by Analytical Psychology and Dante’s analogous journey in the Divine Comedy, integrated into a single path. From the symbols of the Fire and the Light, the authors uncover the psychic elements that act as a trait d’union between the two versions of the process: Dante’s poetic-narrative version and Jung’s psychological-analytical one. After identifying their conceptual differences and similarities, they propose that two such similar representations, made by authors so distant in time – about 700 years, demonstrate that some basic principles, the so-called Basic Rules of life, are like fixed stars in the inner firmament of mankind, as they are not subjected to the wear of time and perennially represent the warp and weft of the psychic and spiritual reality of humanity as a whole.
