The essence of Creation is the fact that, beneath the empirical, observable "real world" is the realm of potentials and our physical world is manifested out of the underlying potentialities by our perspective. The "gift of Free Will" of the Creator is our ability to CHOOSE our perspective. We can choose "living water" that becomes "a spring of water welling up continually within," to "eternal life/creation," or we can choose the water from the "well of Jacob the supplanter," which will leave us thirsty again and again. And it is in this choice that we come to the remark of Don Juan "... As awareness reaches levels higher than the toes, tremendous maneuvers of perception become a matter of course."
Such a choice is a "maneuver of perception," though it is only in retrospect that I can even say this. I was as ignorant of what was happening to me as a person could be.
Further maneuvers of perception amount to the ability to make every choice based on "seeing the unseen." Every time we choose, based on knowledge/love, rather than chemical/emotional love or assumption/wishful thinking love, we are giving a push to the swing of amplifying our Frequency Resonance Vibration. And such amplification increases our polarization and we "grow."
The problem is, in the beginning, when we begin to use discipline to try to "see the unseen," we are like a blind man stumbling through a maze. We are Theseus in the lair of the Minotaur, guided only by the thread of Ariadne. Our ability to perceive the Noumenal world, the activities of 4th density, requires great attention, great discipline, and an ability to "face with serenity odds that are not included in our expectations." We have to learn the art of "facing infinity without flinching." And it is this process that the Cassiopaeans are facilitating. What they tell us about the Noumenal world, the 4th density realm, is not supposed to terrify us in the end, it is supposed to wake us up to the odds that are facing us that are NOT according to our expectations.
And, as we begin to learn to really SEE, we begin to make some experimental choices based on what we are seeing. Some of them work, some of them don't. We adjust our course gradually, learning what amplifies our polarity and what damps our polarity.
