I think this from the Diamond Sutra expresses the same notion.
金刚经 第七品 无得无说分
“须菩提!于意云何?如来得阿耨多罗三藐三菩提耶?如来有所说法耶?
”须菩提言:“如我解佛所说义,无有定法名阿耨多罗三藐三菩提,亦无有定法,如来可说。何以故?如来所说法,皆不可取、不可说、非法、非非法。所以者何?一切圣贤,皆以无为法而有差别。”
(7) "Tell Me, Subhuti. Has the Tathagata attained that Perfect Enlightenment which Transcends Comparisons? If so, is there something about it that the Tathagata can teach?"
Subhuti answered, "As I understand the teaching it cannot be attained or grasped nor can it be taught. Why? Because the Tathagata has said that Truth is not a thing that can be differentiated or contained and therefore Truth cannot be grasped or expressed. The Truth neither is nor is not.
