White powder gold. Hmmmm.... It makes me think of the fungus Claviceps purpurea or "ergot" which is found on rye in perticular. Nostradamus is said
to have used it to reach his state of awareness. Cereal grasses like weat and rye has been looked uppon as gold throughout history, and when you think
about that '___' has much of the same compounds as this fungus... well.... it could be this.... Only the fungus itself is black, but I don't know how
it looks when it has been through all the processes it needs in order to be "safe" to take as a psychedelic drug...
Exactly what I was going to suggest.
It could very well be that they were eating a flour that was contaminated by the ergot fungus. There would have needed to be something else added
though to prevent ergotism (black death).
'___' has many of the properties stated earlier.
Enhanced metal clarity and focus
Positive emotions and greater sense of inner peace
Increased intuitive powers and sixth sense stimulation
Greater insights into self and life situations
Ability to deal with stressful situations from a higher perspective
Deeper prayer and meditative states
Enhanced and/or lucid dreams
Accelerated manifesting and serendiptiy
Right/Left brain balance
Feelings of expansion and access to higher Universal knowledge.
Trust me I did a LOT of research
As far as the Nexus article goes....
Don't you think someone in mainstream media somewhere might have picked up on a substance that can blink in and out of existence?
