The Norse mythological World Tree Yggdrasil represents the matrix of the cosmos, and the state of the universe is reflected by the state of the Tree - it embodies the mythological cycle. It also has intimate connections with life, fate and death and is a powerful life-giving force and symbol of regeneration (like all vegetative symbols). It serves as a medium for gaining knowledge, perhaps due to the oracular powers of the serpent-entwined cosmic trees of many cultures. It is a gateway to other worlds, the material of creation and destruction.
