6.10

第四明行相者。初二解脫作不淨行及無相行。第三解脫作淨行及無相行。空處解脫既緣空境作空行相及無相行。識處解脫作緣識行及無相行。後二解脫可知。若約寬通起無常等諸行。第八解脫既無所緣亦無行相也。

Fourth, explaining the cognitive modes (ākāra): the first two liberations form the cognitive mode of impurity and the cognitive mode of signlessness. The third liberation forms the cognitive mode of purity and the cognitive mode of signlessness. The liberation of the base of space, since it cognizes the object of space, forms the cognitive mode of space and the cognitive mode of signlessness. The liberation of the base of consciousness forms the cognitive mode of cognizing consciousness and the cognitive mode of signlessness. The latter two liberations can be understood [by extension]. If spoken of broadly, they give rise to various cognitive modes such as impermanence. Since the eighth liberation has no object of cognition, it also has no cognitive mode.
