I don't agree however, that being vegetarian makes one more spiritually attuned then a non-vegetarian. To think of the countless tribes that exist to this day, where little is known about their existence, who preserve humanity and commune with nature deeper then your every day millennial. Their structures, which are emerging in documentaries and other unpopular sources eat meat but do so with reverence. We are all human. To say we are more advanced then a native tribe is perspective. What happens when our own advances as a society collapse? Who is better off then?
The shaman, hunter, gatherer, these are people who understand the laws of nature more so then I. Their respect for the natural world has cultivated a deep spirituality in their community and in themselves. ....
i just read something by Sri Yukteswar; ..."men gain a calmness of mind which every psychologist knows is the most favorable to mental activity and to a clear understanding, as well as a judicial way of thinking.... this is done by natural living on a non-irritant diet.
Eric i do not think we have a historical corollary to compare too as a whole group of people living in a spiritual manner. So in this sense you are drawing conclusions about native tribes who live close to nature without considering highly evolved civilizations. We are unable to presently study (with accuracy) these highly evolved civilizations as readily as some of your examples. However that does not mean they did not exist. So... we must also keep in mind
that there were very high civilizations on this earth at times in the past
and there will be again who express an ability to rise above their tribal and hunter tendencies. We presently live in a period of rapid change-the dwapara yuga- when we pass thru this period we will enter much higher periods in which natural living of the past will have little or no relevancy to the spiritual evolution in those higher millennia.
