仁王經疏 2.205

2.205

釋曰：第二、釋所由。緣空為境，故言空慧。行相寂靜，無能緣所緣相，故名無緣觀。前云無相定者，顯所依定；此句即顯能依觀智。前迷心惑，緣心為境，故能斷智還觀心空。無量報者，現所觀境，無量三界心報。

Commentary: Second, explaining the reason. Taking emptiness as its object, it is called 'empty wisdom'. Its functional aspect is tranquil and quiet, devoid of the marks of grasper and grasped, hence it is called 'non-objective contemplation'. The previous mention of 'markless concentration' revealed the supporting concentration; this phrase reveals the contemplation-wisdom that relies upon it. The previous delusions confounding the mind took the mind as their object; therefore, the wisdom able to cut them off in turn contemplates the emptiness of the mind. 'Immeasurable retribution' refers to the object presently contemplated: the immeasurable mental retributions of the three realms.
