Quoted from " Return of The Warriors " by Theun Mares

"What I found baffled me enormously, for it
soon became clear that current credibility appears to be focused
upon books channeled by either discarnate beings or extra-
terrestrial intelligences.

After all, if a man is a liar whilst in a physical body, why should he
suddenly speak the gospel truth once he is disembodied?
Likewise, who in their right minds would trust an extra-
terrestrial being, who is totally unknown, to be unequivocally
superior to mankind in intelligence?

John Lash has some very good information which is useful for self examination of one's own blindness and willful acceptance of things better left out of ones personal belief system.
I highly advise reading his sight in detail.
Here is one of several pertinent links:

I know of a wise Toltec, Don Miguel Ruiz who says don't necessarily believe what I say.
He is right about this, because what you believe in begins to take on form in this dimension.
Careful where you put your energy is his message.

I know of  another sage guy named Wilde or something like that who say something like....
" Its not what people know, but what they think they know that becomes dangerous."

Now to add something critical to both those ideas that many may not have considered.....they are both referring from one angle to how things get created on the non-physical level that then come to affect the manifest realm over time. Many bad ideas carrying on way past their usage date because of the way they are " invested " in. This deals with the Toltec aspect of the Tonal.

until later
