Query: Practical and helpful

I've been reading self-help & spiritual books for a long time. I found this book so very helpful, because it gives you pracitical, "how-to"explanations that are straightforward and easy to understand, rather than just philosophical ideas, that can then get lost in translation to practical application. The ideas in this book helped coalesce many of the random ideas I've read elsewhere, bringing them together into a coherent systematic whole that makes sense.I highly recommend it to anyone trying to grow or deepen their spiritual life.
