四、關內舊解不思議解脫云：「六地斷結，與羅漢齊功，七地侵除習氣，八地習氣都盡，道觀雙流，名不思議。正習俱盡，名為解脫也。」近代南土諸法師解不思議解脫，終傍前解釋，雖復小異，大意終自是同，今不具述。

Fourth, the ancient explanation from within the Pass says of inconceivable liberation: 'Severing the fetters at the sixth ground equals the achievement of an arhat; eroding residual habit-energies at the seventh ground and exhausting all habit-energies at the eighth ground, where path and contemplation flow together in parallel, is called "inconceivable". The exhaustion of both primary [defilements] and habit-energies is called "liberation".' In recent times, the various Dharma masters of the southern lands in explaining inconceivable liberation ultimately follow this previous explanation; although there are minor differences, the general meaning is ultimately the same, so it is not detailed here.
