This book was lovely. It's and excellent reference/guide-book for all, from those just beginning their spiritual journey to those who just wish for a deeper connection.
As someone who was brought up Catholic, I really enjoyed the descriptions of the saints. I grew up being told to pray to various saints, so it was nice to read some of their backgrounds. It was a little interesting and strange that so many of the saints are associated with roses.
As far as the book structure, it would be helpful if the picture and description placement were more consistent. Maybe it was made more difficult because I read this as an e-book, but it would help to have all of the illustrations first and then the description, or vice versa, instead of switching it every so often. Having inconsistent placement can leave the reader a little confused in e-book format as to which illustration belongs to which description.
I didn't care for the fact that under Oshun's "associated culture" section it listed African. Under the "about" section, it clearly states that she is a Yoruba goddess, so her associated culture should be Yoruba. This is the same for Yemaya, who is a Nigerian goddess (presumably of various Nigerian cultures?), and placed under the "African" culture. Africa is too diverse and full of wonderful, varying cultures to place them all under one umbrella like that. In contrast, the Egyptian gods and goddesses were clearly labeled as Egyptian in their culture section, despite Egypt being just as much a part of Africa as Nigeria and Benin (where the Yoruba peoples live).
Kwan Yin is also a Chinese name for one of the Bodhisattva. It seems incorrect to label her Indian/Asian.
Overall, this was an excellent book covering a wide array of spiritual guides, god(desse)s, and various other spiritual beings. The illustrations were gorgeous and truly added something magical to the book. I loved that the descriptions of each being was separated into sections (associated cultures, what they will help with, how to invoke them, and an about section). This made the descriptions easy to follow, and it would make them easy to refer to when in need.
