Power exists in many forms. There is the gentle power of a small brook that gently wears a path into the soil. There is also the incredibly strong power of a massive waterfall. Northern Mysteries & Magick (revised and expanded edition of Leaves of Yggdrasil) by Freya Aswynn is a book that is almost shocking in the strength of the power it exhibits. If you have any interest in learning about the magick and spirituality of the people of Northern Europe, this book is a must. In it you will learn about the runes and how to do runic magick. You'll do divinations and create rune charms. You'll discover the secrets of shamanic techniques such as shape shifting, while learning the secrets of drumming and chanting according to the ancient ways.
