[93] "Rādha, whatever is suffering (dukkha), there you should abandon desire (chanda) for it. And what, Rādha, is suffering? The eye, Rādha, is suffering; there you should abandon desire for it. Forms, eye-consciousness, eye-contact, and whatever … with eye-contact as condition … or neither-painful-nor-pleasant—that too is suffering; there you should abandon desire for it. …
"The mind is suffering; mental phenomena (dhammā), mind-consciousness, mind-contact, and whatever feeling (vedanā) arises with mind-contact as condition—whether pleasant, painful, or neither-painful-nor-pleasant—that too is suffering; there you should abandon desire for it. Rādha, whatever is suffering, there you should abandon desire for it."
