What are the dharma objects apprehended by the mind consciousness?

Among the fifty-one mental factors (caittas), the wholesome mental factors, the afflictive mental factors, and so forth are associated not only with the mind consciousness but also with the manas. The mental sense-objects (dharma-viṣaya) that the mind consciousness takes as its object include material mental sense-objects (rūpa-dharma-viṣaya), mental mental sense-objects (citta-dharma-viṣaya), and at the same time also mental sense-objects that are neither material nor mental—the twenty-four conditioned dharmas not associated with the mind (citta-viprayukta-saṃskāra).

Material mental sense-objects are related to form; form is formed from the seeds of the four great elements, and whatever is related to the seeds of the four great elements belongs to material mental sense-objects. Whatever is related to the seeds of consciousness, related to the eight consciousnesses, or related to the mental factors (caittas) belongs to mental mental sense-objects; apart from these, everything else is mental sense-object that is neither material nor mental. When the mind consciousness takes as its object mental mental sense-objects such as its own afflictions of greed, anger, and delusion, this belongs to the introspective function of the mind consciousness—it is the self-validating cognition (svasaṃvedana) of the mind consciousness. When the mind consciousness observes the mental factors of other consciousnesses, this belongs to the perceiving-aspect (darśana-bhāga) and self-cognition (svasaṃvitti); what is taken as object in all these cases is mental mental sense-object.
