The Marvellous Primordial State is what it is, but it is also the title of a book to be published by Shang Shung Publications this summer. It is a translation of a tibetan text done by a group of translators under the supervision of CNN. I found the excerpts from the book so marvellous that I decided a donation to sponsor the book would be a fine thing to do. Info on the book, and the link for sponsoring it can be be found on the Shang Shung Publications homepage.
I have never heard of this text before, and the author is not mentioned, so it would be interesting with some more info.
