This is a book from the Ancient Practices Series, I'm not sure which book it is, but they are all very good & do indeed help you understand the Christian religion alot better, and explains the history of the Christian holidays, like the book The Sabbaths. Its got side notes that are helpful, and one stood out to me when I first skimmed the book, it says "Spiritual practices are about life, about training ourselves to become the kinds of people who have eyes & actually see, and who have ears and actually hear, and so experence....not just survival, but LIFE." That is the truth, for sure. I look forward to receiving more books in this Ancient practices series to learn more & hep me understand the path of Love of the Christian path.
