The priestess

The second chapter of Meditations on the Tarot takes the traditional representation of the High Priestess card and turns it into a metaphor for the mystic, where the figure represents the transfer of spirit into philosophy. The experience of pure, spontaneous creation goes through the stages of “gnosis” and “magic’ on its way to being transfixed in a material fashion as Hermetic philosophy, or the “book” on the lap of the High Priestess.Meditations on the Tarot, Chapter II- The High Priestess – CRYPTIC COCKTAILS. https://crypticcocktails.com/2020/07/08/meditations-on-the-tarot-chapter-ii-the-high-priestess/
As the Magician is standing vertically, representing the vertical nature of the spirit, the High Priestess is seated, forming the intersection of the spirit and the material. Through the three tiers of the tiara she wears, the pure experience descends into consciousness, or rather; "Spirit must become divine Breath in place of arbitrary, personal activity, and Water must become a perfect mirror of the divine Breath instead of being agitated by disturbances of the imagination, passions and personal desire."Tomberg's Meditations on the Tarot, p. 30
