“Understanding the physiological and neurological features of spiritual experiences should not be interpreted as an attempt to discredit their reality or explain them away. Rather, it demonstrates their physical existence as a fundamental, shared part of human nature. Spiritual experiences cannot be considered irrational, since we have seen that, given their physiological basis, experiencers' descriptions of them are perfectly rational... All human perceptions of material reality can ultimately be documented as chemical reactions in our neurobiology; all our sensations, thoughts, and memories are ultimately reducible to chemistry, yet we feel no need to deny the existence of the material world; it is not less real because our perceptions of it are biologically based... It is not rational to assume that the spiritual reality of core experiences is any less real than the more scientifically documentable material reality.”

“Our belief in a world external to ourselves, filled with things and people that are not us, is an overwhelming fact of our existence. But similarly, our absolute certainty that there is more to reality than just this physical world is a spiritual fact that bears more truth than any other in our lives. We seek to explain this spiritual nature as some metaphysical reality, accepting the constraint of Science that will not allow for any usurpation of the actuality of the physical universe. And we flounder trying. Once we allow our thoughts to be forced into some metaphysical realm, we find ourselves stripped of that single most important validation of spiritual truth – the undeniable presence at the heart of our existence. This is the spiritual truth that we seek, and it is not to be found in the physical reality of Science. The physical reality of Science is to be found in it! “An Introduction to Awareness” is a philosophical journey that takes the reader into the heart of this pure presence of nondual reality – a reality in which the spiritual is not metaphysical, but actual, in which physical reality is 'a machine in the ghost'. This pure presence that we cannot deny is the awareness that lies at the heart of our experiences and thoughts. This irrefutable truth is used as a starting point in a processual analysis of awareness, and of our ideas about existence and self, leading to a clear understanding of the nondual nature of reality as the pure presence of non-individuated Awareness.”

“This is the power of myth: that we can experience invisible spiritual realities and truths greater than visible, material things in story form.”

“However, the natural symbol, without our being sufficiently conscious of the fact, is identical with the reality of the world that appears to us, for every object in the natural world is at the same time a symbolic reality to us. The psyche certainly does not use an "object" of nature as a "symbol," but rather the experience of an "object" itself is always already symbolic experience. The star or tree in us is no less real and no less symbolic than it is in outward experience. For each possibility of experience either presupposes a spiritually forming, that is to say a symbolic activity, or is identical with this. That is, everything spiritual appears to us first not just in nature but as nature; or we could formulate this just as well the other way around: everything natural, whether outward or inward, appears to us as an image, that is to say as formed spirit. We are surrounded by images, inwardly and outwardly, but at the same time formed and determined in all our experiences by the natural symbol as though by a unitary natural-spiritual reality, for our psychic system only grasps that which appears to us as the real world through the world of natural symbolism.”

“Spirituality is the poetry of our experience. Science is the gauge of our reality. Together, they create the essence of our humanity.”

“... while our world is reluctant to call something evil, it has also grown cynical about the possibility of unselfish love. The denial of Satan's existence comes out of a mind-set that denies the reality of the spiritual world. But if the world is purely material, then all action is interpreted as self-centered and we have no basis for love. The denial of evil eventually leads to the assumption that there is no love.”
