I really couldn't put this book down. It covered everything from Celtic, to Wicca to the Fey.
The visualizations at the end of each chapter are exceptional.
I plan to use them very soon.
It was a very enjoyable read.
While I would have to agree with the other viewers on the "oneness" that is often focused on in this book, overall it is a wonderful reference for anyone interested in celtic spirituality.
Knight takes the time to delve into topics covered in most other celtic themed books, such as the Druids and Faeries. What I particularly enjoyed was the fact that modern celtic traditions were mentioned, as well as the what the future might hold for these traditions.
This isn't a book that is heavy on rituals or spells, and that was a nice change of pace for me. It seems all the books I ready today are spellbooks and the like. The focus here is what goes beyond and is behind those rituals that we read.
The author has a very easy to read format, and I think that even if you're just starting out you won't get too bogged down in terminology and format.
I recommend this is a great beginners book, as well as a quick reference to those who are more experienced.
