2.142

六、究竟乘者，即是無學智阿羅漢、辟支佛、佛所得非想第九解脫道盡智、無生智、佛如實智，能運入無餘涅槃也。

Sixth, the ultimate vehicle: this is the wisdom of the non-trainee—the knowledge of exhaustion, the knowledge of non-arising, and the Buddha's knowledge as it truly is, attained on the path of liberation of the ninth [level of] neither-perception-nor-non-perception by arhats, pratyekabuddhas, and Buddhas—which can convey [one] into nirvāṇa without remainder.
