The 2012 Mayan Apocalypse is now called The 2012 Phenomenon. I believe Quatrain VIII-71 pertains to the sensationalizing of December 21st, 2012 and the end of the Mayan Long Count Calendar. The Mayans had merely predicted the beginning of The Eschaton.

Nostradamus Quatrain VIII-71
Croistra le nombre si grand des astronomes,
Chassez bannis & livres censurez,
L’an mil six cens & sept par sacrées glomes,
Que nul aux sacres ne seront asseurez.

Nostradamus Quatrain VIII-71
A growing number of great astronomers
Chased out, banished their books censured:
The year sixteen hundred and seven [1607-2012] by consecrated assemblies,
Such that none will be assured from the sacred.

Essentially, to Immanentize the Eschaton is to bring about heaven on Earth even if it means slogging it down the hard road of The Apocalypse.

Terence McKenna was an ethnobotantist and philosopher known for his exploration of psychoactive drugs used by indigenous cultures around the world. He came to believe that the human species was moving toward a Great Attractor in time. He called it The Eschaton; it is the point when The End Times begin.

…Terence McKenna’s original date of The Eschaton, November 16th, 2012, has also come and gone. On that date Israel bombed the headquarters of Hamas in the Gaza Strip just after a visit by the Egyptian Prime Minister.

…McKenna arrived at his date through a fractal algorithm of time he developed based on the dropping of the atomic bomb on Hiroshima, Japan, which occurred on August 6th, 1945. McKenna’s Novelty Theory proposes that history is shaped by periods of novelty – when our regular, mundane days are suddenly reshaped by some novel event, like the dropping of a nuclear bomb somewhere close to where you live…

The American Presidential election was on 11/06/2012, The Petraeus Scandal erupted on 11/09/2012, and then Terence McKenna’s original date for the commencement of The Eschaton was on 11/16/2012.

I suspect that “their books censured”, “such that none will be assured from the sacred” refers to the failure and disappointment when doom did not arrive as hyped by various media and alternative media sources and the critics and skeptics had a field day with the, “I told you so’s“.

The failed interpretations of “a number of great astronomers” left many people questioning their “sacred books”.

I think this interpretation is another major success of my solving the dating code, unfortunately it came well after the fact. Clearly, we see the 1600 Series of prophecies appearing in both The Quatrains and The Sixains, and this is ample proof that these poems are connected.

I now see the importance of The Petraeus Scandal in relation to The Eschaton. The Triplicate Series, Quatrains X-75, X-76, and X-77 are certainly allusions to former General David Petraeus and his cadre of Generals – some who are presently employed in the Administration of President Donald J. Trump.

Whatever the true events behind The Petraeus Scandal, around November 16th, 2012 The Apocalypse was set in motion.

I have also finally come to understand the symbolic importance of McKenna’s Eschaton. The Apocalypse, The Kali Yuga, Ragnarök, doom is hardwired into the human psyche. Our lifetimes are weighed in this ultimate heavenly judgment at the core of humanity’s major religions.
