This volume proved to contain Book Two, the Unknown Books of the Essenes and Book Three, the Lost Scrolls of the Essene Brotherhood.
I haven't read Book One, the Gospel of Peace of Jesus Christ, so I'll have to try and get hold of that now.
These two Books I've read have, understandably, been translated (from the Aramaic ? - it's not clear) into an English comparable perhaps to that of the Authorized Version of the Bible (perhaps not, but that's what it seemed like to me).
I could have wished for a more detailed explanation of who the Essenes were. There is only a brief description of them, explaining that they lived on the shores of lakes and rivers, were agriculturists with their own economic system, and having neither rich nor poor amongst them. Jesus was of course an Essene Master.
The various texts can at first seem a bit unappealing, not being in modern language, but they are wonderfully poetic and contain much wisdom. After reading a few pages, my mood became elevated, though I felt good to begin with!
I recommend these texts to all those with any interest in spiritual matters.
