" You are what we think…geez, that’s frightening!" – Lily Tomlin
Humans are believers. We consistently mistake belief for knowledge. We are “built” that way, and that has a pragmatic and ad hoc use. Nevertheless, the inherent faults we commonly incorporate into our thinking, of which there are primarily six, prevent us from experiencing a greater degree of one-to-one correspondence of our thinking with reality/Reality. An impartial examination, I believe,

, of history relative to faith, religion, and philosophy made form a standpoint of connecting dots of a Universal theme reveals a thread of the idea of transformation. It takes many forms, but is generally pointed to by the myth of the Hero who descends into hell or a hellish situation, and emerges victorious united with his Love.
These are wonderful stories, but have the remarkable feature of accommodating the growth of awareness from surface perceptions through to the greatest “spiritual” maturity possible for a a particular individual. Indeed, that, like all teaching tales and koans, is the point of their being. They are a lozenge of distillation of metaphysical experience coated in the appearance of what ultimately is the “red pill.” Pious religiosity is, alas, despite its advertised result, the “blue pill,” those colors referring to the well known Matrix movies, the first of which actually had some value in the genre of myth.
I have heard, though, that even as few as one in a million can actually penetrate the veils by use of the map factor of myths. Generally they are just good stories until that moment when one is seized with need or with the descent of insight which yields another perspective and meaning regarding these “stories.” Christianism in general has lost and as a body of faith refuses to restore the mythic value of the Jesus story, even in the case of those who have been able to move from the pious literalism of their faith even to the psychological, let alone the metanoic possibilities of the underlying Way inherent in the foundations of exoteric faiths.
In this regard, when we look at the myth of the “fall” of Adam, it can be seen that it is at least a symbolic representation of the development of human awareness to that stage from which it is possible to distinguish self from sense and environment. We are yet, even in our times and this culture, in the midst of this struggle, being held back largely by notions offered as the basis of christianist faiths.
The alleged “fall,” as I see it, is tied into the alternate understanding of the “fall” of Lucifer as well. Both have to do with the state of awareness. In one case, Adam, it is the development of the ability to be self observant and to distinguish categories and degrees of separation and manipulability, both internally in the psych, and externally in the world. This translates, perhaps, as the development of tools of perception, manipulation, and most importantly communication, that latter being the greatest proof of commonality of the permeable nature of awareness as based on a common or Unitary Consciousness which may be called “Source.” In the case of Lucifer, it is the symbolic loss of the feeling of Being “I AM” as the foundation of interpreting the world. Physical reality overlays Being with a sense of duality, which though not Real, in the sense of unchanging and foundational, appears relatively real in terms of pragmatism relative to physical survival.
In any case, the Church has abandoned, for whatever reason, the metanoic values of these myths and by popularizing the surface story of their christianist incarnation, have caused a tragedy of inconceivable proportions. That tragedy is the loss of opportunity for many to transcend their sense involvement with the physical world and re-assess their identity in terms of the underlying Invisible Reality of the manifest world.
This entire question rests on the understanding of the simplest and most common of words: “I.” Experiencing Right Identity is the Key, if one is capable, to understanding and living from the premise pointed to by the Teachings attributed to Jesus. His teachings are demonstrably identical to what might these days be called The Perennial Philosophy, though it has and is known by many labels, none adequate and all misleading. Many factors, from degree of faith to intellectual acumen, through information regarding even grammar, psychology, phenomenology, general semantics, religious history, etc,etc, and even unto downright grace and insight, can all factor into this re-assessment, voluntary or not, of Identity.
But though this all has been a clumsy and incomplete attempt to delineate some form of answer to your question, I can finally only say that it is all a matter of waking up. That is the whole point, in my estimation, of the Law of Love and both forms of the Golden Rule. If you know the “other” as yourSelf, how can you do harm, and how can you not support? The stories of the Bible and other holy books and all of esoteric mythology point to the whys of our condition today and to the Way of remembering who and what we, in Fact, are.
