i'm new here.
The following information has not been presented. Or at least to my knowledge.

As you know the Rosetta Stone is the key to deciphering Heiroglyphics. That's our one logical fact. It seems apparent that everyone is making the connection between "Lost Keys (Blame Hofmann)" and "Rosetta Stoned;" understandable. So what is the connection? Everyone seems to be on the LSD kick, lets forget about that and Albert Hofmann altogether, for a moment.
So there was another guy named Hofmann and if you care to search, his name gets hits with the Rosetta Stone. Mark Hofmann was a professional counterfieter in the 1970's and 80's. He made numerous forgeries of mormon documents. One of which was a copy of the golden tablets which were translated to create the book of mormon. Hofmann's document was basically Heiroglyphics from the Rosetta Stone merely rotated in a way and a few extra pen strokes added.
The next step. These golden tablets which ultimately founded the mormon religion were not just "found." Joseph Smith was visited by an angel, a celestrial being, an alien what have you, and was told of these tablets and where to find them. He translated the tablets and we now have the book of mormon.
There's a just a foundation for you. You can go and do your own research and piece a meaning together.
What is the true meaning behind the lyrics, i don't know, probably wont ever, unless Maynard sits down and tells them. That's not important to me. What's important is how I and you and everyone else who accepts the sounds from the album in and how their conscious or subconscious not only reacts, but interacts with it.

Thank you for your time.
