I found this book well set out. It is written by a highly experienced practitioner who knows how to talk in simple Delia Smith style step by step terms. It works with empowered visualisation, using well illustrated tarot cards as a starting point. The system is rooted in celtic spirituality, embodied in Arthurian legends. The learner is taken steadily and without rush, through the four elements and many of their permutations and associated characters. The course lasts a year, but can be joined at any point. For someone wanting to begin a daily spiritual practice, I found it very helpful. It does not subscribe to a dualistic view of the spiritual world, so is not suitable for people who hold strong dualistic opinions. However, for the very many Christians and others who do not belong to the strongly dualistic wing, this book holds no terrors. It introduces and works with entities and mystery situations normally referred to within Christianity under angelic names, and much of which would have been familiar in various guises, to early Christians. This is a personal comment; the book does not take time out to discuss Christian correspondences to its Arthurian content. The previous reader's comments about having to buy the cards separately hold good. However the effort is well worth while.
