"That is why instead I went back to my own body, and my own feelings of what is beautiful, whole, and right. The result was that I returned to eating meat."

Has it ever occurred to you that your "own feelings of what is beautiful, whole, and right" constituted a return to what you were taught to do during your most formative years of childhood? Seems kinda hard to me to buy the whole "shamanistic" hand waving when we have a perfectly adequate explanation in your childhood programming.

Sometimes, as we grow and learn more about the world around us, we get the urge to refrain from doing everything that simply "feels right", because we realize that our own personal feelings are not the end-all and be-all of creation. Sometimes our deepest desires can hurt those around us if we give them no guidance. Its a hard path to follow, striking out against the mold you were poured into as a child, and its very easy to relapse. So I can't entirely blame the self-serving attempt to dismiss those who disagree with you:

"Eisenstein has given in to self-indulgence, hedonism, and general moral turpitude. He has abandoned his principles to revel in his own selfish pleasure. Shame on him!"

Why do you "feel" the need to transform a reasonable outlook into a ridiculous parody? Is it so hard to admit that you like the taste of meat enough that the minor ethical concerns you have about it just aren't enough to stop you? Hey, fine, eat meat, in the grand scheme of things it won't matter anyhow. The least you could do is be honest with yourself in the process, rather than disguising your motivations with a thin glaze of eastern religion.
