The extreme external focus lends itself to the idea that they either don't realize they have access inward to the Source of All, or that they don't want it that way, and are trying to devise a way to eternal life through the outer.
Constant loosh replenishment via human beings' emotions and whatnot... seems to be a temporary plan while they keep looking for a way to "get the perfect body" (heh... interesting connection to societal focus, I just noticed) that is self-sustaining through self-will, rather than Divine Will. I'm sure it doesn't pass their notice that they are actually subservient to their need for that loosh via others, and that human beings can and do become "inedible" by acquiring knowledge that alters their frequency. It is likely what they see as their "one weakness", this need to refuel via the existing Creation.
If you've ever repressed a fear and later on chose to face it, or if you remember the first time you faced a fear, you might recall the sense of dread and "fear of fear" that you had to encounter before getting on with the process. It requires a willingness to feel one's vulnerability and face the unknown.
My sense is that these Beings have a very strong, very long-standing wall up to "surrender" or anything that would engender a sense of weakness, vulnerability or "subservience" to something "other". This is also evidenced in their tendency to make others subservient to them. Feeling weak or vulnerable is repulsive to them, it seems.
As we frequently recognize, life the STS way, our 3D experience, is "fear-based". My sense is that it stems from this essential fear just mentioned. Seems to be a fear of facing their darkness, facing the idea that they are fueled by fear... which boils down to basically a fear of facing their Creator. Not that they see it as a fear, of course. It is more a refusal to acknowledge something by believing it isn't true, never looking at the cause for their refusal but instead believing in it fervently. Thus the "wishful thinking" term.
With this fear at their base or as their "fuel" for Mind, their thinking is skewed. This is the mind they gave us, so to speak, and which is enforced in every "civilized" structure, institution, organization and system mankind lives with. The impediments we experience to our own growth - those times and ways that we refuse to acknowledge a weakness or falsehood from which we're taking action, the times we seek data and information in order to be "right" and "in control", rather than seeking truth for enlightenment - these are our hints to the root of what makes them tick or what constitutes the STS ways.
Maintaining repression of nearly half of one's own innate Divinity (the feminine, their feelings, the inner pathway to Source) requires "feeding" off the material nature (Material, Maternal, Mater, Matter - the feminine) borne of the Divine anyway, but it seems they haven't or don't want to make that connection. Or they have but refuse to believe it, or refuse to believe that it has to be that way (again, wishful thinking).
Ever intent on remaining separate and gods unto themselves, they seek a way to "make a reality" for themselves where they reign supreme, so as to never have to acknowledge a god greater than themselves. They desire "equal status" with the Ultimate Creator, yet are attempting it from partial Self status.
Or so I seem to sense...
