Grammatical Analysis
Nāmarūpa: [nt.] mentality-materiality; name and form; mind and body. Formed by nāma (mind, name, bending) + rūpa (matter, physical form).
Orthodox Definition
Nāmarūpa represents the entire psycho-physical organism of a sentient being. In the chain of Dependent Origination (paṭiccasamuppāda), it constitutes the fourth link, conditioned directly by consciousness (viññāṇa-paccayā nāmarūpaṃ) and serving as the direct cause for the six sense bases (nāmarūpa-paccayā saḷāyatanaṃ).
To maintain strict Abhidhamma precision, the commentaries isolate the components:
- Nāma (Mentality): In this specific causal link, nāma does not include consciousness (which is the preceding link). It refers strictly to the associated mental factors (cetasika), specifically the core components: feeling (vedanā), perception (saññā), volition (cetanā), contact (phassa), and attention (manasikāra).
- Rūpa (Materiality): The physical body generated by kamma, specifically the four great elements (mahābhūta) and the sensitive material receptors forming in the womb.
They arise together like two sheaves of reeds propping each other up; neither mind nor body can exist in the sensuous planes without the support of the other.
