The Arising of Form Through Delusion's Grasping of the Realm

Original text from the Laṅkāvatāra Sūtra: As for the other consciousnesses, they arise and cease—the mental faculty, consciousness, and so forth. In every moment, they manifest the arising and ceasing of the seven consciousnesses. Due to unreal delusions, they grasp at various objects and realms, at diverse forms and appearances. They attach names and concepts, unaware that the forms and appearances perceived are merely manifestations of their own mind. Unaware of the suffering and happiness [that arise from this], they fail to reach liberation. Bound by names and concepts, greed begets further greed.

Explanation: Apart from the Tathāgatagarbha with its inherently pure nature, all else—such as the mental faculty and consciousness—are subject to arising and ceasing. Sentient beings, in every moment, manifest the impermanent nature of the arising, ceasing, and transformation of the seven consciousnesses. Because they do not know the true reality of the Dharma realm, they give rise to unreal delusions, grasping at perceived realms as real, grasping at the diverse forms and appearances of the six dusts (sense objects), and then attaching names and concepts to them. Unaware that all these perceived realms and appearances are merely illusory phenomena manifested by the inherently pure mind, they remain ignorant due to this lack of understanding. Thus, they fail to realize the suffering and happiness brought about by clinging to objects. Where there is suffering and happiness, liberation cannot be attained. Since beginningless time, sentient beings have been bound by worldly names and concepts, giving rise to all kinds of afflictions arising from greed and attachment.
