It is well known that in most shamanistic cultures, the use of hallucinogens was quite prevalent in order to access the Trance State more easily. Although the above extract mentions that certain geometric forms were seen under the influence of certain drugs, it is also mentioned that schizophrenic hallucinations allowed those going through this state, to see the grid. The grid and similar geometric patterns are known as ‘Entoptic Phenomena.’
The word ‘Entoptic’ is taken from the Greek and means “Within Vision.” Entoptic phenomena are internal visual sensations, which originate within the visual system – anywhere from the eyeball to the brain cortex. Here’s another extract from the same book:
‘Certain effects like phosphenes seem to derive from occurrences within the eyeball, and cellular excitation of the retina. (And possibly elsewhere within the visual system,) but much of the imagery or form constants seems to originate in stimulated neuronal firing deeper within the visual system of the brain. Full iconic, representational, hallucinations seem to draw on memory imagery from deep brain function, which combines with, and then habitually obliterates the underlying geometric structures. (It has been speculated by some experienced researchers that the memory material elicited may not only relate to the personal history of the individual, but to transpersonal cellular and even species memories.) It is worth special note that entoptic images seem to be stronger under hallucinogenic trance than in other kinds of trance states.’
Now going back to early man’s use of these powerpoints in the grid: After a while, stones were placed at these points on the instruction of the shaman, and this was another instinctive leap forward: These standing stones or 'menhirs' as they are called, acted very much like the acupuncture needles that are used in the same meridian channels of energy that connect together all the organs in the human body. Like the acupuncture needles, they found that these stones could stimulate the flow of energy at the location of these crossing points. It was only later that these points also became connected in some way to the positions of the stars.
The matrix created at these points therefore became 'magnetic centres' which could attract by the sympathy of their vibration, the same desired events which had been play-acted within them, and so ensured the habitual success of capture. The power of visualisation which has been explained in much detail in new-age literature was also used. This explains the many carved figures and cave paintings that were made, helping early man to advance the power of imagination and visualisation. This was where art had originated, and the real importance of art came into being.
