The Intrinsically Pure Mind Transcending All Realms of Form, Sound, Smell, Taste, Touch, and Dharmas

Original text from the Śūraṅgama Sūtra: If you obstinately cling to the discriminatory perceptions, awareness, and observations, considering the nature that understands and knows to be the mind, then this mind should exist apart from all activities of form, sound, scent, taste, touch, and other dusts, possessing its own complete nature.

Explanation: If you cling to the mind that discriminates form, sound, scent, taste, touch, and dharmas—the mind that perceives the six dusts and observes the six dusts—insisting that this must be the originally pure self-nature mind, then this mind should exist independently, separate from all realms of form, sound, scent, taste, touch, and dharmas, retaining its own complete characteristics. It would not arise with the presence of the six dusts nor cease with their disappearance. This means the mind should be inherently free, originally present—not a mind that emerges only when the six dusts exist.

But since that mind of discriminatory perceptions and observations ceases to exist when separated from the six dusts, it cannot be the originally pure self-nature mind.
