Paul Devereux - The Tukano and Choco Indians - 'Entoptic geometry'
Type of Spiritual Experience
A description of the experience
Paul Devereux – The Long Trip
It seems that the [Turkano] Indians are able to engineer environmental cues and make use of bodily and emotional states to encourage and enhance the occurrence of entoptic phenomena. During these flashback periods, they see the physical world overlaid with entoptic geometry, and it has been experimentally confirmed that when seen in this combination such patterns can take on a more definite form. G Reichel-Dolmatoff was able to photograph Indians tracing out entoptic geometry on the sand.
……….Reichel-Dolmatoff noted that Choco Indians over a thousand kilometres to the north west of the Turkano have developed a similar entoptic art style, and they too take Banisteriopsis [a hallucinogen].
“The pottery of a prehistoric burial cave in northern Columbia associated with snuff tablets and bone containers suggesting the use of narcotic snuff is [also] decorated with designs clearly comparable to the Knoll-Turkano series” [according to Reichel-Dolmatoff]
