The Gatha on the Transmission of the Dharma by the Thirteenth Patriarch Kapimala

The Dharma that is neither hidden nor manifest is called true reality;

To realize this Dharma of hiddenness and manifestation is neither foolish nor wise.

Explanation: The Tathāgatagarbha itself does not deliberately conceal itself to prevent sentient beings from knowing it, nor does it deliberately manifest itself to enlighten sentient beings. It possesses no such mental activities. It is sentient beings who are foolish or wise—the foolish fail to recognize it, while the wise perceive it clearly. Regardless of whether sentient beings see or do not see, recognize or do not recognize it, the Tathāgatagarbha truly exists, neither arising nor ceasing, never changing. It is the sole reality within and beyond the three realms.

Upon realizing this Dharma of the Tathāgatagarbha, which is both hidden and manifest, one understands that it is neither foolish nor wise. It is free from ignorance, greed, hatred, and delusion; it is not confused by any phenomena. Yet it also lacks the worldly wisdom of the three realms—it does not know all phenomena, does not discriminate among them, does not calculate, analyze, ponder, or reason, and does not act as a sovereign ruler. It merely manifests phenomena according to conditions without grasping them.
