The Diagram of the Tree

The Diagram of the Tree (עץ). 

The word עץ is not just a label; it is a vertical map of the spiritual structure.

The Canopy (Top): 

The Letter ע (Ayin) This is the Crown. The Ayin is the Eye. It is the power of Vision and Imagination. Before a thing exists in reality, it exists in the "seeing of the mind"—the Ayin receiving directly from the Divine. The leaves represent the Se’aros (שערות)—the sensitive filaments of the mind. They are the "hairs" of the intellect that reach up into the void to catch the flash of Divine intuition. The Ayin envisions the potential; it sees what does not yet exist

The Rooting (Bottom):

 The Letter ץ (Final Tzadik) The ץ is not a separate entity; it is the Ayin extended downwards. Visually, the upper form remains unchanged—it is the same vessel of vision. But structurally, it deepens. It is a changeless support that transforms in sound and reach, not in sight. It takes that celestial imagination—the vision caught in the mind's eye—and extends its leg deep below the line. It does not hold the vision high in the abstract.It pulls the imagination down through the trunk, past the surface, and plants it into the soil.Here, the Tzadik becomes Yesod Olam (יסוד עולם)—the Foundation of the World—grounding the Divine imagination into the bedrock of reality.

The Tree (עץ) acts as a conduit: 

It envisions the Divine in the Ayin (the mind's eye/se’aros).It humbly drags that vision down into the earth with the Tzadik (the roots). It is the act of seeing the highest light and burying it in the lowest soil to give it life.
