This video explores the concept of "galdr," a traditional form of Norse magic or incantation. The speaker explains that galdr involves a specific, often repetitive, way of vocalizing words to connect with deities and spirituality. The discussion differentiates galdr from runes, highlighting that while runes have fixed meanings, galdr allows for personal creation and intent within the incantation. The speaker also touches on the three parts of a galdr incantation: calling upon deities, stating the purpose, and affirming the result.
