In Norse cosmology, Yggdrasil is the axis mundi, the world axis that connects all realms and serves as a point of stability in a constantly changing universe. Its roots, branches, and trunk symbolize the interconnectedness of all life and the cyclical nature of existence.

Yggdrasil embodies the duality of life and death, representing the eternal cycle in which life emerges, flourishes, and eventually returns to the earth. The tree’s roots reach into the realm of the dead, emphasizing the connection between the living and the deceased.

The branches of Yggdrasil stretch into the heavens, while its roots delve into various realms, symbolizing the reach of life beyond physical boundaries. This duality reflects the idea that life is not just confined to the earthly realm but is part of a larger cosmic order.
