On not-self, existence, and ontological strategies

Of course hence all ariyans except Arahants still have the delusion of conceit (I am) which is a lingering habituation of self, which requires recursion of seeing no-self clearly to remove. Hence the sutta (pottpada sutta I think) on when one sees the no-self of intention and thus it is better to not intend, one attains Arahantship. This means self habituation (i.e. conceit) of the aggregates (i.e. clinging) is removed gradually.
