Moreover, these sentient beings must have also discarded all arbitrary ideas relating to the conceptions of a personal self, other personalities, living beings and a Universal Self, because if they had not, their minds would inevitably grasp after such relative ideas. Further, these sentient beings must have already discarded all arbitrary ideas relating to the conception of the non-existence of a personal self, other personalities, living beings and a Universal Self. If they had not, their minds would still be grasping after such ideas. Therefore, every disciple who is seeking Anuttara-samyak-sambodhi should discard, not only conceptions of one's own selfhood, other selves, living beings and a Universal Selfhood, but should discard, also, all ideas about such conceptions and all ideas about the non-existence of such conceptions.
