Basically there are two ways of attaining the jhanas : by focusing on a concept which is considered the arya way.
Or, by focusing on a – let’s call it so – “material” support as breathing etc, which is considered anarya way.
In both cases the high degree of absorption obtained, despite based upon intellect (association and integration) is somehow beyond it; i mean the result as jhana is beyond it.
Now what i just said seems to contradict/exclude the anarya way for what has breathing to do with intellect ?
