It occurs to me that our belief system, which we rely upon, is also, like ego, largely built from what we have been told by others, not first hand experience or careful study. In fact, all that we know is from others. So both are full of errors. Back to Buddha: do not believe anything you have been told until you have tested it yourself, and if you find it to good, right, and true, then adopt it and live up to it.
So not only are our egos misleading us, so is our belief system. Silence. We can have no opinion without due consideration. Anything we say is built on either ego or belief system, or knowledge. The science is good, if it is well done. Food science is at best shaky.
Where does this leave one?
