Why is the “underbelly” of the deep subconscious so soft? It appears to tirelessly protect the beliefs of the individual from direct alteration with logic and argument, while apparently being a “sitting duck” for easy and extensive manipulation and alteration by the interlopers. Was this a divine design flaw?

The defect in question is not our doing, but alteration done by the interlopers. After all, having created the human physical body and the genetic components as well as the energetic layers providing the template for the physical expression in terms of the morphology as well as the interplay of consciousness coming from the higher self and generated by the individual’s non‑local consciousness, all of that architecture can function superbly according to the original blueprint. What has happened has been an alteration to damage things—that was done deliberately through a genetic distortion of the human race to cause this fragmentation of the mind. So the fact the deep subconscious can be impaired when under attack relentlessly by interlopers in a covert fashion unobserved by the higher levels of consciousness, creates victims who then are condemned to live within a body tormented deep within with high levels of stress and much impulsive behavior being generated by what dim impulses get through from the deep subconscious. This is all a product of pathology stemming from the external manipulation by the interlopers. Anything beautiful and majestic can be tampered with or even destroyed through application of sufficient energy. If an advanced extraterrestrial species blows up a world of beings like humans, you cannot say: "This is a divine design flaw." They were simply vulnerable because all energy can be changed through interaction with other energy under the right circumstances. The end result may be positive or negative, so one must look to the intention behind that energy, where it is coming from and why, and this will show where the fault lies, whether it is a consequence of a divine plan or decision or a consequence of neglect or manipulation done in the pursuit of evil intentions, as by the interlopers in your world.
