The Intrinsically Pure Mind Is Free from All Realms of Form, Sound, Smell, Taste, Touch, and Mental Objects.

Original text of the Śūraṅgama Sūtra: 若汝执吝分别觉观，所了知性，必为心者，此心即应离诸一切色、香、味、触诸尘事业，别有全性。

Explanation: If you are attached to the mind that can discriminate, the mind that can feel the six sense objects, the mind that can observe the six sense objects, and insist that it must be the originally self-natured pure mind, then this mind should be able to leave behind all these realms of form, sound, smell, taste, touch, and dharma, and still have its own complete characteristics in existence; it should not arise with the arising of the six sense objects, nor cease with the ceasing of the six sense objects. This means that this mind should be a free and unconditioned mind, a mind that exists from the very beginning, and cannot be a mind that only appears because the six sense objects exist.

However, that mind of discrimination, initial application and sustained examination (vitarka-vicāra) no longer exists when it departs from the six sense objects; therefore it is not the originally self-natured pure mind.
