Is the world coming to an end in 2012? According to the Mexica calendar, which is less known than the Mayan calendar, but dates back to the same period, this is - of course - actually not the case. The calendar carries on for another 13,250 years, and describes some cycles of time bigger than the ones mentioned in the Mayan version. These cycles are based upon the revolution of our Sun around the Pleiades, and are formed by smaller cycles called “the Suns”, each lasting 6,625 years. During the transition from one sun to the other, i.e.: from one cosmic configuration to another, the influence of both suns is equally present for a short while, as is the case when the seasons change. Although the dawn of the “Monkey Sun” started in 1991, the previous sun shall maintain its prevalence until the 21st December 2012, when the two energies shall be in perfect balance. Subsequently, the old sun will lose its strength, and from 2021 its successor shall reign unaided for a thousand years. If up until now man has attempted to impose his domination over nature, under the new sun he will have to comply with her and this shall lead to great transformations affecting both the individual and the collective consciousness. The instructions on how to withstand the changes are issued now, at the precise time stipulated by the Mexica prophecy, by the custodians of an uninterrupted oral lineage which opens itself to the world here in written form for the very first time. This book contains several breathing exercises taken from the Mexica oral tradition, some of which are designed to provide relatively easy access to some altered states of consciousness.
