Let me say as clearly and as intensely as possible that the Esoteric dimensions of Man cannot be perceived by ones brain or physical senses.
The reason for ones MIND doing this is not capricious nor accidental. The reason for ones MIND doing this is part of the Purpose of Life. Ones MIND, in other words, does what it does because it is supposed to do what it does as part of the overall Purpose of Life. But ones MIND, and the Purpose of Life are Esoteric, and thus exist and operate beyond the reach of ones brain and its ability to perceive what is going on. Ones brain is incapable of perceiving ones MIND or ones Spiritual realm. And to imagine that neither of these Esoteric realms are important just because ones brain cannot perceive them is... nuts. That is, a part of ones MIND that specializes in denial of Reality. You can research this part of the MIND Here.
There is a "REASON" for this structure. And this reason is known by mystics, and was also known by the ancient Greeks who gave us the term Psychology. Only one of these realms [the physical realm] is part of the physical universe. You might want to read the last sentence again!
I suspect you have never considered that two-thirds of yourself are part of other regions of Creation, have you? Your MIND realm is composed of a lower MIND [whose energy is of the Astral plane of existence], and a higher MIND [whose energy is of the Causal plane of existence]. Of course neither of these are part of the physical realm, which means your physical brain cannot perceive these two "other worldly" vibrational realities. You do not have to have experienced what I am speaking about to abstractly realize how silly it is to imagine that one could use ones brain to perceive other dimensions of Creation.
If you can appreciate that the MIND is beyond the reach of the brain, then you can appreciate how ones Spirituality [the vibrational Energy of which cannot be perceived by even ones MIND] is far too subtle for ones brain to perceive.
Again, the reason for this is not capricious, accidental nor without purpose. Ones Soul is composed of what I refer to as Neutral Spiritual Energy, or NSgy. This NSgy is an Absolute Energy. It cannot be harmed, is permanent, and cannot be other than it is, ever. It is the Energy of God, of ones Soul, and of Truth, Love and Acceptance. And oddly enough, just think a moment about how, if you were NSgy, you would know who you were, or what you could be? You are Neutral Spiritual Energy, emphasis "Neutral". Neither this, nor that. For the brain, this would mean "nothing".
Given this situation, it is not surprising to me that God would conceive of the process of projecting a part of NSgy as the Creation, and then populate it with Souls that, when the final phase of Creation was "ready" as the physical universe, and a planet of that universe was "ready" to inhabit by Souls as living organisms, such organisms would begin the process of Life. Then to make sense of the process of discovery by the Souls, God issued the Law of Karma that would become a part of the MIND of every Soul that commits to Life.
The MIND, the Spiritual realm and the Law of Karma are all Esoteric realities that are Absolute in structure and operation. That none of these can be known by any physical faculty is simply a matter of physics. The only way one can become aware of these Esoteric dimensions of Reality is to do so via ones faculty of "intuition", which is an aspect of ones Apapsyche , which is part of ones Spirituality, and a special part of ones Soul.
Does the reader comprehend what I am saying here? I am saying that it is not possible to use ones brain and thinking to perceive ones Esoteric dimensions. And the reason for this is perhaps too simple to comprehend? Ones brain is physical. That is, tangible, and ones brain can be proven to exist scientifically. So, being physical ones brain [thinking] is not "Unknown" and thus, it is "safe", familiar and comfortable. And, those who are most intellectual [due to compensation ] are limited to their brains and thinking to understand life. This means they are heavily invested in pushing the notion that there is nothing ones brain cannot discover.
What I am attempting to do here is to offer a basic rationale for the idea held by many people that there is nothing the brain cannot "know". A seemingly strange paradox exists wherein ones MIND [which is not physical] causes ones brain [which is physical] to "think" that there is nothing ones brain cannot "know" or discover.
The Whole Human Being is composed of three simultaneously existing vibrational realms of separate energies, all of which share the same time and space, which I designate as the Whole Human Being, or WHB. From "inside" out, these realms are said to be the Spiritual realm; The MIND realm; And the physical realm.
The process of fulfilling the Purpose of Life is to accumulate completed Karma which is a slow and painful process that takes many, many lifetimes. This of course means reincarnation. To comprehend what "Awakening" means, one must set aside some beliefs and prejudices that are widely held among the population.
