Indeed! You may find a direct parallel to this so-called "spectrum" with the concept of the seven major
chakras, from the root (red) to the crown (violet). In fact, the author of that book was channeling information from his "Higher Self," if you will, that was referring, in part, to the
chakra spectrum of consciousness.
This is, of course, nothing new, for NOTHING is actually "new" in Cosmic (Divine) Consciousness.
Nothing is really new, but everything is really now.
No person actually "originates" an idea, friend. Very few humans have ventured to realize this, yet there can be no Self-realization without realizing it. This information you speak of has been known by various entities in various civilizations throughout many eras in many dimensions, and none of them originated it of themselves, for there are no separate minds in creation. All minds are really but perspectives of the One Infinite Mind.
This information was known in many ancient human civilizations, used in conjunction with many ancient technologies. Much of human science fiction is based upon soul remembrances of these times, both in terms of Earth incarnations as well as those in other planetary systems and dimensions.
"There is nothing new under the sun." Nor above it.
