The elite players that have ruled our world have had this knowledge from the beginning  7:1 Jesus said: The Pharisees (politicians) and the Scribes (lawyers) have received the Keys of Knowledge, they have hidden them. They did not enter, and they did not let those enter who wished. I think there is much un-tapped knowledge deemed unprofitable by the 'cabal'.  As indicated in the quote from the Gospel of Thomas (discredited by the Vatican); this has been the case for around 2000 years.
