2.1080

意云：煩惱之本即是身心，若執身心，煩惱何斷？故標斷煩惱，釋以身空。又斷盡煩惱，空却身心，身心尚空，根塵何有？

The meaning is: the root of afflictions is precisely the body and mind; if one clings to body and mind, how can afflictions be severed? Therefore, stating the severing of afflictions is explained by the emptiness of the body. Furthermore, having severed all afflictions and emptied body and mind, if body and mind are already empty, how could faculties and objects exist?
