From the author of Helrunar: manual of rune magick, and Visual Magick, a handbook of freestyle shamanism, comes the definitive study of magical trance and possession techniques. The author is inspired by the Nordic tradition of Seidr, said to have been taught to the human race by Odin. The book provides an extensive survey of the manifestation of this powerful technique through several related magical traditions - shamanism, mesmerism, draconian cults and even the nightside of European paganism. Seething is probably the most useful magical technique I have ever learned. I first was taken by the pleasure of it. My body felt warm and sensual, and seething in the hips felt quite sexual. I liked the feeling of my body taking over where the shaking was first voluntary - but I could still have some control, making the shaking stronger or more subtle. After a while I started to see visions - something that very rarely happens to me. I could see (with my physical eyes, not astrally!) the surface of the land in the centre of the circle rippling, like waves of energy. It was a really moving experience in a site that - until then - had not been particularly 'special' to me... it ..has had a major impact upon my magical work which used to be largely indoors, as at last I have found a way that I can work outdoors. This gives my magical work a potency that it simply didn't have before. - Shantidevi quoted in chapter twelve 'Rhythms and the Mind'
