yep, you could just simply say that nothing exists not even buddhism or the buddha
but as long as there is a subjected conceptual self and the experience of suffering, and birthing - kamma, then there is effectively a soul - a continuum of the habitual
james brown may indeed have no soul, but conventionally speaking it's obviously real enough, despite having no actual substance
just because a bike isn't real doesn't mean that it can't be ridden
this is where words fail, and the sound of one hand clapping comes into play.
a lot of talk is about things that are not currently relevant leading to perpetuation of gross ignorance and cyclic entrapment
although a stumbling block may not actually exist, it would be wise to pay it some attention if you keep tripping up on it sweep the non-existant rocks of the non-existant path
