仁王護國般若波羅蜜多經疏 2.141

2.141

解曰：心行處滅者，心緣慮息也。言語道斷者，言說不及也。同真際等法性者，謂波斯匿王觀身實相，體同真際、量等法性。然諸有情無始時來為我法倒熏習力故自他差別，由業力故所感身形六趣差異；論其實相，皆同真際等法性矣。從此第三結觀如來。

Explanation: "The place of mental activities is extinguished" means that the mind's cognitive deliberation ceases. "The path of words is cut off" means that verbal expression cannot reach it. "Identical to the limit of reality, equal to dharmatā" means that King Prasenajit, contemplating the real mark of the body, found its substance to be identical to the limit of reality, and its measure equal to dharmatā. Now, all sentient beings from beginningless time, due to the habituation of the inversions regarding self and dharmas, have distinctions between self and other, and due to karmic force they experience bodily forms differing across the six destinies; but considering their real mark, all are identical to the limit of reality and equal to dharmatā. From here is the third, concluding the contemplation of the Tathāgata.
