Msseeker, what he meant is that developing a healthy body also develops one’s spiritual abilities. We are a combination a guf and neshama and the health of one is dependent on the health of the other.
Derech, WE do hold by his deyot and sheetot. Your statement about non-acceptance is circular – you say that he is not accepted by those who do not acept him. BTW, by saying that his sheetot are irrelevant you are guaranteeing that in the end your sheeta will not be the Halacha (Eruvin 13b).
