Dr. David R. Hawkins, MD, PhD developed a "map" of the levels of human consciousness (also called the Scale of Consciousness) that uses a muscle-testing technique called Applied Kinesiology (AK) to document the nonlinear or spiritual realm.
The research was scientifically validated and published in Dr. Hawkins’ doctorate dissertation titled Qualitative and Quantitative Analysis and Calibrations of the Level of Human Consciousness, an elaborate discussion of the Scale of Consciousness and its significance as outlined in his groundbreaking book, Power vs. Force: The Anatomy of Consciousness (Veritas Publishing, 1995).
Briefly, each level of consciousness (LOC) coincides with determinable human behaviors and perceptions about life and God. Each level represents a corresponding attractor field of varying strength that exists beyond our three-dimensional reality. There’s a critical point within each LOC from which its field gravitates (or entrains).
The numbers on the scale represent logarithmic calibrations (measurable vibratory frequencies on a scale which increases to the tenth power) of the levels of human consciousness and its corresponding level of reality. The numbers themselves are arbitrary; the significance lies in the relationship of one number (or level) to another (e.g., Dr. Hawkins’ scale is from 1 to 1000).
