Behind your thoughts and feelings, my brother, there stands a mighty ruler, an unknown sage-whose name is self. In your body he dwells; he is your body. There is more reason in your body than in your best wisdom. And who knows why your body needs precisely your best wisdom? (Chapter On the Despisers of the Body)
I believe this quote can be successfully interpreted without reading the book or even the verses that come before or after it, since it seems to be independent & self-contained.
I interpret this as he's saying that the mind and body are one, that the brain is just another organ of your 'body'. He probably didn't believe in a soul and he may be right since the complexity of the brain seems commensurate with the nature of our minds.
"...best wisdom" would refer to the wisdom of the mind. To attain wisdom, one uses reasoning. He makes the claim that there's more reasoning in your body (all of your organs) than the reasoning your mind used to attain your best wisdom. Does this reasoning of the body possibly refer to the fact that cells in your body are underpinned by logic which is underpinned by maths which is 'reasoning' in its most rudimentary form? One of the products of this 'reasoning by the body' is your mind which created your 'best wisdom'.
At the end he says nobody knows why your body would do this, which is strange because surely it would have to do it in order to help the body to survive since wisdom by definition aids this.
Is my analysis right or wrong? Why?
