俱舍論疏 29.53

29.53

The passage of the treatise starting with "The path of liberation in the threshold stage... until: only then is it called liberation" explains that the path of liberation in the threshold stage of the sphere of boundless space, because it objectifies the sphere of boundless space, receives the name 'liberation'. Because the uninterrupted path objectifies the lower stage, it is not called liberation, since it does not turn away from the lower. The Nyāyānusāra has another explanation: "The nine uninterrupted paths and eight paths of liberation of all threshold stages are also not liberations, because they do not turn away from the lower stage, because they are intermingled with paths objectifying the lower, and furthermore because one is not yet completely freed from the defilements of the lower stage (above is the text of the treatise)."
