In this discussion I support entheogenic-gnosis. True, I do not have any factual prove that the ancients did extract and smoked DMT. But the reason I believe they did is something else.
Please do not mind me getting off topic. What I have noticed since smoking DMT is nothing more than recognition. To put it clear: in trips I have seen many old Chinese looking palaces, Greek temples, human like beings with animal heads, dragons, angels etc.
What I think is that the ancients created their culture based on what they encountered in hyperspace. The similarities are all around us. Just wander around in Italy, Greece, Peru, China.
The resemblance is too overwhelming not to see a connection.
Quiet the mind and the soul will speak
