Recipe for Bliss certainly conveys the many inner experiences and insights one gleans from a spiritual path, but for the seeker of knowledge Schmidt's prose proves to be more cryptic than clarifying. If you are serious about learning technique this book is not the one to buy. Kriya technique itself is probably best left to those who are the original disseminators of this meditation path , namely Paramahansa Yogananda's Self Realization Fellowship.
Not a book to buy online, without looking through it first. If you want to learn the technique of kriya yoga, you'll get a recipe for disappointment. Schmidt doesn't teach technique at all. He muses and rambles in a soft-headed, soft-hearted way, about a lot of New Age Old Hat amalgamated with quasi-Christian notions. If you're a member of Schmidt's immediate family, by all means, buy it. Otherwise, try The Sacred Science by Paulsen.
