Sixth, regarding the explanation in terms of the four-knowledges gate: the first two phrases explain [the knowledge that] "my births are exhausted"; "attained their own benefit" explains [the knowledge that] "the brahma-practice has been established"; the knowledge "exhausted all fetters of existence" explains [the knowledge that] "there will be no receiving of further existence"; "their minds attained mastery" explains the knowledge that "what was to be done has been done."
