In 1971, the McKenna brothers went down to a remote part of the Amazon jungle to
investigate rumours that the shamans.
After a shared hallucinatory episode, the brothers returned to the USA to develop the insights they had in the Amazon. They were convinced that the ancient Chinese oracle - the I Ching, or Book of Changes - worked because it was a mathematically coded form of the time wave system that underlies change in the universe.
The I Ching is a group of 64 six-line structures called hexagrams, which show all combinations of Yin and Yang (like + and - ). Another researcher - Martin Schonberger, in 1973, found an exact correspondence between the 64 hexagrams and the 64 codons in our DNA...
Eventually, they found a complex fractal wave, where each level is 64 times greater than the one below, consisting of 26 levels, which describes all change in the universe, from sub-atomic event durations, up to a universe-length time-span.
When they analysed the peaks and troughs of history, and lined up the Timewave over the wave of history, they found that the end of the wave, when all the sub-waves peak together, will be in the year 2012 !! At the time they discovered this, THEY KNEW NOTHING ABOUT THE MAYAN CALENDAR, or that the Long Count ends in 2012.
The Invisible Landscape was published in 1975, and knowledge of the Mayan calendar did not become widespread until 1987
