維摩經玄疏 3.216

3.216

八不動地，即是別教辟支佛地。地論師云「從此明無學道」，未知的出何經論。不但八地得無生忍，寂而常用，用而無相，無功用心，自然斷法界無明惑，色習盡也。

The eighth ground, Immovable, is the ground of the pratyekabuddha of the distinctive teaching. Masters of the Daśabhūmika say: "From this point the path of no-learning is explained," though it is not yet known from which sūtra or treatise this definitively derives. Not only does the eighth ground attain anutpattika-dharma-kṣānti, but being quiescent yet constantly operative, operative yet without characteristics, with an effortless mind, it naturally severs the delusion of ignorance regarding the realm of reality, and traces of form are exhausted.
