““In the same way, reverend, purification of ethics is only for the sake of purification of mind. Purification of mind is only for the sake of purification of view. Purification of view is only for the sake of purification by traversing doubt. Purification by traversing doubt is only for the sake of purification of knowledge and vision of what is the path and what is not the path. Purification of knowledge and vision of what is the path and what is not the path is only for the sake of purification of knowledge and vision of the practice. Purification of knowledge and vision of the practice is only for the sake of purification of knowledge and vision. Purification of knowledge and vision is only for the sake of extinguishment with no fuel for grasping. ”
