Person's can achieve relative 'peace' or 'freedom', person(personae) means mask, a concept if you wish, so it is not possible to get anywhere or achieve anything like that  hence freedom is from the notion of person-hood with which one identifies, so 'practice' to be are of be identified with what is not so, or what is false or merely conceptual at so many levels, that awareness of dis-identifying with the conditioned self is 'required' not as a 'doer' then the veils are removed one by one  or like an onion, peals are removed and in the end there is no-thing there..it is an effortless effort..any way these are more words!
