The mystic and the physicist arrive at the same conclusion; one starting from the inner realm, the other from the outer world. The harmony between their views confirms the ancient Indian wisdom that Brahman, the ultimate reality without, is identical to Atman, the reality within.

Quantum mysticism is a term that has been used to refer to a set of metaphysical  beliefs and associated practices that seek to interconnect mystical world-views to quantum mechanics  and its scientific interpretations.  Both metaphysics and quantum mechanics are looking for the "fundamentals of Reality, one starting from the inner spiritual realm, the other from the outer physical realm. 

Research in the field of quantum physics indicates that we may understand reality and the interconnection of all things from a logical scientific perspective.  Mysticism however tends to imply that while we may experience all the phenomena in the world as manifestations of the same ultimate reality, the true nature of that reality cannot be empirically understood or defined. The maxim in the opening line of the Tao Te Ching ; “The Tao that can be expressed is not the eternal Tao”, affirms the mystic belief that the true nature of reality transcends our intellectual concepts and defies explanation.  Mystics say that the nature of existence can be seen, but it cannot be grasped, which is exactly what the physicists say about the nature of atomic particles. 

Therein lays the main difference between physics and metaphysics.  Physicists believe that you can understand and explain reality; mystics believe that if you can explain it then you don’t really understand it. 

A page from a journal of modern experimental physics will be as mysterious to the uninitiated as a Tibetan mandala. Both are records of enquiries into the nature of the universe.

For many the term “metaphysics” is synonymous with the term “science fiction”.  For those who are not familiar with the fundamental concepts of physics the theories of quantum mechanics seem no less fantastic.  The idea that we may exist in an infinite number of universes, where an infinite number of possible actions may result in an infinite number of outcomes, seems to be so incredibly improbable that the human mind, in order to maintain its sanity, cannot accept it as possible, which may explain the fundamental experience behind the concept of the Shamanic Ecstasy. 

The role of the shaman is to be "the vision seeker" for the community.  It is the role of the shaman on his shamanic journey to travel beyond the realm of the material, into the realm of the immaterial, in order to encounter the people, animals and spirits that inhabit other realms of the Universe.  While on this journey, to those viewing from the journey from “the outside” the shaman seems gripped by an incomprehensible madness, while the shaman on “the inside” is experiencing a different reality, separate and distinct from the perceptions and experiences of the one from which he has traveled.

It must certainly be allowed, that nature has kept us at a great distance from all her secrets, and has afforded us only the knowledge of a few superficial qualities of objects; while she conceals from us those powers and principles on which the influence of those objects entirely depends.

The term "quantum physics" is derived from the latin word "quantus" meaning "how much" and Greek word "physika" which means "of nature". 

The term metaphysics is derived from the Greek words "meta" which means "beyond" and "physika" which means "of nature". 

Together they attempt to ask the same question; “How much is still beyond what we now know of nature?” 

Quantum physics attempts to explain how everything in the Universe, in all dimensions of life and reality consists of "quanta", of "energy", of the vibratory nature of sub-atomic particles in "String Theory". 

Metaphysics attempts to explain how everything in the Universe, in all dimensions of life and realityconsists of "prana", of "Qi (or Chi) energy", of the "vibratory nature of reality". 

Together they attempt to provide the same answer; “There is only one reality and that is the one that exists in your own consciousness, in your own quantum mind and both physics and metaphysics appreciate this reality equally well.”

Whenever the essential nature of things is analyzed by the intellect, it must seem absurd or paradoxical. This has always been recognized by the mystics, but has become a problem in science only very recently.
