The book begins in August 1987 on the slopes of Mount Shasta in Northern California as Borax witnesses the Harmonic Convergence, a spiritual and astrological event sparking a 26-year countdown to 2012, the year that marks the end of history in the Mayan calendar. Signs indicate that a major energy shift is occurring, a turning point in Earth's collective karma powerful enough to change the global perspective of humankind.

Borax's mountaintop experiences compel him to seek solutions to his personal turmoil. He meets Lonsdale and together they launch a mystery school to study how the twenty-five-year period between 1987 and 2012 can be used for a cosmic purging of negativity to release humanity's core forces and restore universal balance. En route, Borax and his fellow students discover truths about life after death, karma, reincarnation, past lives, human evolution, and the purpose of our existence on earth. In the tradition of The Teachings of Don Juan, Carlos Castaneda's tales of his shamanic master, 2012: Crossing the Bridge to the Future is a gripping sorcerer's apprentice story driven by mystical forces, encouraging readers to expand their everyday awareness and challenge their fundamental beliefs about their place in the universe.
