The bible has been manipulated in so many ways that the original teachings are a contradiction in themselves. Here is a quote from the Bible and an explanation of what it means.
"For I tell you truly, he who kills, kills himself, and who eats the flesh of slain beasts, eats the body of death. For in his blood every drop of their blood turns to poison; in his breath their breath to stink; in his flesh their flesh to boils; in his bones their bones to chalk; in his bowels their bowels to decay; in his eyes to scales; in his ears their ears to waxy issue. And their death will become his death."
The Essence Gospel of Peace, Book 1.
I know the acidic negative effects that animal flesh has on your bowels, blood and in turn to your body. I know that the acid from animal protein (uric acid, nitric acid) gives rise to bacteria, yeast and mold and all sickness and dis-ease. I know that boils and pus created by bacteria and yeast comes from animal protein acid. I know that to buffer the double loss of alkalinity from eating animal protein the body leaches calcium from the bones causing osteoporosis. Look into an old person's eyes, they are not white, they are a cloudy, consistency from the bad formation of blood in the bowels, which, in turn, makes eye cells. Again, how did the ancients know this?
