In physical experience you are dealing with an environment with which you are familiar. You have completely forgotten the chaos and unpredictable nature it presented you before learning processes were channeled into specific directions. You learned to perceive reality in a highly specialized fashion.

When a personality realizes that such other realities exist and that other experiences with consciousness are possible, then he activates certain potentials within himself. These alter electromagnetic connections both within the mind, the brain, and even the perceptive mechanisms. They bring together reservoirs of energy and set up pathways of activity, allowing the conscious mind to increase its degree of sensitivity to such data. The conscious mind is set free of itself. To a large measure it undergoes a metamorphosis, taking on greater functions. It is able to perceive, little by little, some of the content before closed to it. It need no longer perceive the momentary blank spots fearfully, as evidence of nonexistence. The fluctuations mentioned earlier are often quite minute, yet highly significant. The conscious mind knows well of its own fluctuating state. When once it is led to face this, it finds not chaos, or worse, nonexistence, but the source of its own abilities and strength. The personality then begins to use its own potential.

Thoughts of peace, particularly in the middle of chaos, take great energy. People who can ignore the physical evidence of wars and purposely think thoughts of peace will triumph -- but in your terminology the work meek has come to mean spineless, inadequate, lacking energy.
674 414 The Nature of Personal Reality

Man’s unconscious knowledge is becoming more and more consciously apparent. This will be done under and with the direction of an enlightened and expanding egotistical awareness, that can organize the hereto neglected knowledge - or it will be done at the expense of the reasoning intellect leading to a rebirth of superstition, chaos, and the unnecessary war between reason and intuitive knowledge.

The idea of a meaningless universe, however, is in itself a highly creative imaginative act. Animals, for example, could not imagine such an idiocy, so that the theory shows the incredible accomplishment of an obviously ordered mind and intellect that can imagine itself to be the result of nonorder, or chaos - [you have] a creature who is capable of mapping its own brain, imagining that the brain’s fantastic regulated order could emerge from a reality that itself has no meaning. Indeed, then, the theory actually says that the ordered universe magically emerged - and evolutionists must certainly believe in a God of Chance somewhere, or in Coincidence with a capital C, for their theories would make no sense at all otherwise. The world of the imagination is indeed your contact with your own source. Its characteristics are the closest to those in Framework 2 that you can presently encounter.

The material is complex and we simply don't have time to read it all. I did not check if there were exercises associated with chaos.

Chaos exists as a probabilty.

Just like everything else.
