Reddit mentions of 2012: The Return of Quetzalcoatl

In the 1890's the Hopi Indians prophesied that in 130 years the U.S. government will slaughter millions of its own citizens. Every prophecy that the Hopis predicted has come true. That includes WW1, WW2, the Great Depression, and others. This was discussed by Daniel Pinchbeck, who lived for almost a year with the Hopis.

Unfortunately, I don't think there is any one link that will help you with that. Let me recommend some books to you that might help:

The Disinformation Guide to Magick and the Occult is one of the most helpful tomes you will ever read. There is an entire section of "Chemognosis," which is to say real knowledge gained through this sort of experience.

There are two books by Daniel Pinchbeck I would recommend reading:

Breaking Open the Head

and

2012: The Return of Quetzalcoatl

There is a clinical study on DMT, called DMT: The Spirit Molecule that is worth reading. There is a movie version of it on Netflix, but don't watch the movie over the book. Do both, but if you only do one, read the book.

There is also a documentary I would recommend watching on Ayahuasca. Watch this documentary.

I wonder if you've ever read this book? The author is very much focused on the concepts of synchronicity and shamanism. At one point he travels to Africa where he takes Ibogaine with a native tribe there. He describes the same tree spirit.

I've not journeyed quite as far as yourself, but your description was enthralling, and many parts of your experience directly match many of the conclusions I've come to during my own moments of introspection. I, like you, am skeptical and tend to question everything, but I think as long as you don't take yourself too seriously, which you don't seem to do, you've got alot of things figured out. Anyway, thanks for sharing.
