Esoteric Meaning
Two pillars appear repeatedly throughout the Major Arcana, most prominently flanking The High Priestess. These are Boaz (the black pillar, meaning 'in strength') and Jachin (the white pillar, meaning 'he establishes'), originally described as standing at the entrance to King Solomon's Temple in Jerusalem. In Freemasonic tradition, they represent the fundamental duality that governs the universe: mercy and severity, light and dark, the active and the passive, the known and the unknown. The figure seated between the pillars occupies the 'middle path'—the point of balance and integration where opposites are reconciled. The High Priestess sits between them as the guardian of the threshold between the conscious and unconscious minds. The Hierophant sits between similar pillars within a structured temple, representing the formal, institutional transmission of the same esoteric knowledge that the Priestess guards in secret. In Justice, the pillars frame the throne of cosmic law, emphasizing that true fairness requires balancing all perspectives. The two towers in The Moon echo this dual motif in a more sinister register, representing the boundary between civilization and the unknown wilderness of the psyche.
