Nice link P.M.  I did not catch this the first time around.  In some respects, it might be more accurate to say that many people have 3 brains, for their left and right hemispheres are consistently imbalanced and not so merged.   

  But yeah, the whole thing about the gut is very important too.  We actually have more serotonin in the gut than in the brain! 

  Re: your article, this is why fasting is such an important activity and practice to engage in at least occasionally.  For it helps to correct digestive imbalances, which then in turn allow the whole system to function more clearly and powerfully. 

  I believe this is why various spiritual teachers from various traditions advocated, or at least personally practiced fasting. 

  Could we imagine a modern day developing Jesus type who gorges himself regularly on Burger King fast food? 

  Maybe its possible for someone to develop to his attunement living in such ways, but it definitely does make it harder and thus less probable since that attunement in our cycle is rather difficult for most to fully reach while in the flesh.

  Perhaps this is why Rosiland McKnights and Cayces guidance both stressed time and time again the need to treat the body physical with respect, to eat healthy, and in both the former and latter info recommended a vegetarian diet for those on a more deep spiritual path? 
The former said that we could enable important energy changes just by cutting down on the amount and types of meat eaten.   They said no body needs a lot of meat nor the heavier types (beef, pork, etc), but anyone would benefit from eating less and eating only lighter meats (foul and fish) if meat was considered by self to be necessary.
