This book presents the first comprehensive description of the Stav tradition, introducing the hidden structure of the Younger Futhark through Stavs blend of philosophy and practice. The third edition includes updated chapters and a strengthened presentation of the author's thesis on the structure of the Younger Futhark, offering new insights into the runic reformation at the dawn of the Viking Age. The previous editions were praised for their clarity and for placing Stav within its Scandinavian cultural and historical context. Stav is rooted in Norse mythology, revealing layers of runic meaning not available elsewhere. Stavs martial philosophy and training provide a practical route to embodied understanding, with breathwork and mindfulness at its core.
