There are numerous proposed theories of ASCs (altered states of consciousness) and mystical phenomena. These range from psychological perspectives (psychoanalysis, transpersonal psychology) and neurophysiology, to cognitive neurosciences, bioneurology, and beyond. [For a review of approaches, see the BLOG section [link to: “Explanatory Mechanisms of Altered States of Consciousness: A Critical Overview”]
Mosaic Kabbalah, while entailing a range of alterations of consciousness (including some of very advanced nature, at higher initiatory levels), occupies its own, unique classificatory niche, or category (see, e.g., Table 1, “Taxonomy of Mystical Experiences” in What is “Kabbalah Religion”).
Mosaic Kabbalah is designated as theistic-numinous mysticism, of the Mysterium Tremendum and monotheistic variety.
One viewpoint, from the neuroscientific perspective, suggests that a progression of “expansions” of consciousness may entail a more intense and/or broader either left- or right-hemispheric brain activity (resulting in “expanded consciousness”).
A more-advanced stage is the unison between the two hemispheres, a more substantial accord between them than is the baseline or normal functioning (this might be designated as “higher consciousness”).
What particularly pertains to Mosaic Kabbalah’s advanced stages is the following: The hemispheric unison suddenly shifts into a dramatically distinctive, elevated state representing a “new quality” and synergy in the hemispheric symbiosis (this might be called “super-” or “hyper-consciousness”).
Much larger cognitive-epistemic awareness and unheard of intellectual and spiritual vistas become available to the initiate, with concomitant intensification and growth of mental, emotional, and spiritual powers.
