[expand]The tree’s threefold division mapped cosmic geography onto natural form:
The roots penetrated underworld realm—the buried portions connected to ancestral domain where dead resided, the root network accessed earth forces originating from depths, the subterranean realm was not evil but necessary foundation. The roots were underground connection to powers and ancestors sustaining visible world.
The trunk occupied middle world—the central vertical section represented human realm where daily life occurred, the trunk was interface between upper and lower domains, the middle position was humanity’s cosmological location. The trunk was human habitation zone connecting divine and ancestral realms.
The branches reached celestial sphere—the upward-extending portions accessed sky domain where divine powers resided, the crown’s expansion suggested connection to solar forces and weather patterns, the uppermost realm was divine residence. The branches were skyward reach connecting earth to celestial powers.
The vertical axis connected all realms—the continuous structure linked domains otherwise separated, the tree was cosmic bridge enabling communication between levels, the vertical organization suggested hierarchical but interconnected reality. The axis was unifying structure preventing complete separation.
The natural metaphor made abstract accessible—using tree form made cosmological concepts immediately comprehensible, the botanical reference connected spiritual understanding to observable nature, the familiar form encoded complex theology. The tree made cosmology tangible.
