96.13

文殊菩薩問法身經云。如言摩尼寶舍有四角。從一角視。悉見諸角。無所缺減。是故見諸本際。釋曰。若了一心本際何法不通。以諸法從心所生。皆同一際。住此際中。一一圓滿。舉目咸是。何待意思。智不能知。言不能及。故云。金剛寶藏。無所缺減。

The Sūtra of Mañjuśrī Bodhisattva’s Questions on the Dharmakāya says: “For example, it is said that a mani-jewel house has four corners. Viewed from one corner, one completely sees all the corners without any deficiency. Therefore, one sees all original limits.”
Exposition: If one understands the original limit of the one mind, what dharma is not penetrated? Because all dharmas are produced from citta, they all share the same limit. Abiding in this limit, each and every one is perfect and complete. Raising one's eyes, everything is it; what need is there to wait for thinking and reflection? Knowledge cannot know it, and words cannot reach it. Thus it says: “The adamantine jewel-treasury is without any deficiency.”
