The tree sacred to the goddess Frigg in Norse mythology is the Yggdrasil or world tree, often depicted as an immense ash tree. This tree connects the nine worlds and is central to the cosmos, symbolizing life, death, and rebirth. Frigg, as the goddess of marriage and motherhood, embodies nurturing qualities linked to the tree’s expansive roots and branches. Yggdrasil serves as a reminder of interconnectedness among all beings and the cyclical nature of existence.
