This little book, in quite simple terms, explains some very fundamental teachings. These teachings are not only Hermetic, but ring true in relation to just about every theological, religious or esoteric study I've made. If you are aware of your spiritual path and wish to advance along it, I highly recommend this reading. I've read it numerous times and find diamonds each time. If you study esoterics, either eastern or western, this is a requirement among the rest of the texts in your library.
