Tell that to the SW Native Americans. Maybe that's why they lost their lands?
Peyote use among native Americans was more common in what is now Mexico than what is now the United States.
The reason the Indians were overrun is that the Europeans had a head start on civilization and all the technology that comes with it. Most of North America was still in the Mesolithic Era, hunter-gatherers. Agriculture had only recently been invented and it was hampered by the lack of easily domesticated animals. It's pretty hard to start right in with the bison as your only native type of cattle. The largest domesticated animal in North America was the turkey. The Aztecs and Incas had invented civilization but it hadn't quite spread across the Rio Grande yet.
All of this is just an accident of history. Homo sapiens arrived in Asia Minor in 70,000BCE, and it took them 60,000 years to invent the first civilization in Mesopotamia. H. sapiens didn't arrive in the New World until about 15,000BCE, with only things they could carry on a long journey, separated from their community, undoubtedly having lost ground both culturally and technologically. Yet it only took them 13,000 years to invent civilization in Mexico and Peru. Not too bad. Still, our civilization had an 8,000 year head start on theirs so when the two came in contact there was no contest. The Europeans' Iron Age weapons and organization defeated the Aztecs' and Incas' Bronze Age weapons and organization as easily as they defeated the Stone Age weapons and organization of the Sioux and Apache.
This is no cause for anyone to feel superior, it was just an accident of history. Unless you're Chinese, Indian, Semitic or Cushitic (basically Ethiopian or Coptic), your people did not invent civilization. You're just the descendant of conquered and assimilated barbarians, no different from the North American Indians. So settle down, Beavis.
Well, where does rastafarianism come from?
Am I the only person here who knows how to use Wikipedia? Ras Tafari was one of Emperor Haile Selassie's many titles. Another one--that and the fact that he was the king of the only independent African nation in the 1930s--cause some Jamaicans still in the Colonial Era to believe that he was the new prophet. Their other prophet is Marcus Garvey. It is an afrocentric faith that has won the hearts of black people all over the world, helped by its ritual use of ganja and its identification with Jamaica's other major cultural export, reggae music. I have never been able to engage a Rastafarian in conversation about his faith, but that illustrates my own opinion that it is a religion more of this world than the supernatural. Rastafarians seem to genuinely care more about peace and brotherhood on earth--with no animosity toward white people--than about scripture and the hereafter.
Despite its roots in the bible, Rastafarianism is more like your definition of an "eastern" religion. It seems to have nothing of Abraham's vengeful, intolerant, violent deity or the racism and bellicosity that characterizes the three main branches of Abrahamism. The fact that Rastafarians consider marijuana to be a staple of every household reinforces your hypothesis.
BTW, what exactly is an "eastern" religion? Judaism, Christianity and Islam all arose in Asia. Protestantism, which the Pope distinguishes from "true" Christianity, is European. Unless you count that and the Mormons, yet another offshoot of Abrahamism, Rastafarianism is the only modern religion to come out of "the West."
I thought L. Ron Hubbard created scientology? Was he on drugs at the time?
Oh crap, I forgot about that one. L. Ron Hubbard was a novelist who created the universe of Thetans and all that far-fetched stuff as a science fiction story. Hubbard also invented a self-help system called "Dianetics." At some point he got the brilliant idea that both he and his system could be much more successful (and much more lucrative) if it could qualify for non-profit status. (For American tax purposes in case any foreign folks are following this.) The best kind of non-profit organization is a church, they get the benefit of the Freedom of Religion thingie in the Constitution and are held to lower standards than the Sierra Club or Alcoholics Anonymous.
Let's see. How to start a religion? How to start a religion? Bingo! He already had one! The science fiction stuff he wrote would make a perfect scenario for the supernatural component of a religion. So he joined his sci fi story to his Dianetics system, named it Scientology, and a new religion was born.
I am not kidding. Our income tax laws are that easy to abuse.
