The tree of life was not botanical illustration but cosmological diagram—vertical axis linking underground realm through surface world to celestial sphere, the tree form encoding cosmic organization in immediately comprehensible image. The tree symbol operated simultaneously as cosmological map, genealogical diagram, and spiritual connection, the multiple meanings layered within single powerful form. The Baltic tree of life traditions preserved understanding that vertical organization structured reality, that roots/trunk/branches corresponded to realms of existence, that family lineages mirrored cosmic structure—the comprehensive system making tree motif central to Baltic symbolic vocabulary expressing fundamental worldview through natural metaphor.
