Also your remark about ‘a body as a one root of illusion’ - I disagree completely. It is my imperfect perception of the ‘higher’ reality that makes me believe that body (as part of all world around us) is somehow separate from ‘me’.
It is not often that I agree with the bombastic one, but... What Szczepan said.
The body shouldn't be neglected or seen in a negative light -- Just seen as it is. And like all creatures we need some degree of care, feeding, nurturing, ... How else did that Buddha guy end up with that gut? :P
