Adamski's Orthon was a sacred Avatar?

George Adamski's Orthon, the alleged Venusian he met in the desert, supposedly left this shoe imprint (with an, as yet, undeciphered message):

Was Adamski's Orthon a reality connected to the Far Eastern gods?

Adamski was familiar with Buddhist and Hindu theology, so did he concoct the Orthon shoe with a kind of reference to such theologies?

Adamski's elaborate hoax is fraught with esoteric and exotic references that either example a brilliant con man or a person who actually touched an ethereal connection to the gods, who interacted with early man (in India and elsewhere) as the Ancient Astronaut theorists would have it?
