Seidr is a form of pre-Christian Norse magic and shamanistic practice, primarily associated with the Norse goddess Freyja. It involves rituals and techniques aimed at divination, healing, and influencing the natural world. Practitioners, often called seidkona (female) or seidmen (male), would enter altered states of consciousness to connect with spirits and gain insights.
The practice of Seidr is characterized by its communal aspect, where participants gather to perform rituals, often involving chanting, drumming, and the use of symbolic objects. It played a significant role in Norse culture, reflecting the society's beliefs about fate, the interconnectedness of all beings, and the power of the unseen world.
