3.84

'It is not that the cognition of the mind ceases': above, in contrast to non-enlightenment, it was called enlightenment, and so one consciousness has two meanings. Now, in contrast to delusion, it is called cognition, and so the One Mind has substance and marks. The marks of delusion of non-enlightenment turn and cease, becoming incipient enlightenment; the cognitive substance of innate enlightenment does not cease, and is non-dual and without difference from returning to the source. Thus far, the explanation of the marks of the causes and conditions of defiled and pure arising and ceasing is completed.
