This, the sixth book in a progressive series by the author, finalizes and further clarifies the true nature and core of the condition termed "Enlightenment." Although it draws on consciousness research for explanation and contextualization, it is primarily an instruction manual for the serious spiritual devotee and reveals information that is known only by those who have transcended the ego to reach Divine Realization. This is the inner route from the self to the Self, and the descriptions of the progressive states are devoted to the reader's own Illumination. The subjective states of the mystic have been of great interest but historically never have been clarified to the degree presented in this semi-autobiographical account that also provides the means by which to identify their rare occurrence and thus describe the core characteristics of Spiritual Truth. Devoid of ecclesiastical doctrine or religious belief systems, the pristine essence of all spiritual Truth is revealed in its purity with unprecedented clarity. It becomes clear that to truly "know" is to "be" rather than to "know about." Why all of Dr. Hawkins' books begin and end with Gloria in Excelsis Deo! becomes apparent.
