This term is used in Buddhism to refer to constituent processes of the human being: nāma is typically considered to refer to psychological elements of the human person, while rūpa refers to the physical. The Buddhist nāma and rūpa are mutually dependent, and not separable; as nāmarūpa, they designate an individual being.[1]
Psychobio constituents
In the Pali Canon, the Buddha describes nāmarūpa in this manner (English on left, Pali on right):
"And what [monks] is name-&-form? Feeling, perception, intention, contact, & attention: This is called name. The four great elements, and the form dependent on the four great elements: This is called form. This name & this form are [monks] called name-&-form."[2]
In keeping with the doctrine of anātman/anatta, "the absence of an (enduring, essential) self", nāma and rūpa are held to be constantly in a state of flux, with only the continuity of experience (itself a product of dependent origination) providing an experience of any sort of conventional 'self'.
Part of the cycle of suffering
Nāmarūpa is the fourth of the Twelve Nidānas, preceded by consciousness (Pali: viññāna; Skt.: vijñana) and followed by the six sense bases (Pali: saḷāyatana; Skt: ṣaḍāyatana). Thus, in the Sutta Nipata, the Buddha explains to the Ven. Ajita how samsaricrebirth ceases:
The term nāmarūpa is also used in Hindu thought, nāma describing the spiritual or essential properties of an object or being, and rūpa the physical presence that it manifests. These terms are used similarly to the way that 'essence' and 'accidence' are used in Catholictheology to describe transubstantiation. The distinction between nāma and rūpa in Hindu thought explains the ability of spiritual powers to manifest through inadequate or inanimate vessels - as observed in possession and oracular phenomena, as well as in the presence of the divine in images that are worshiped through pūja.
^ For example, Rhys Davids & Stede (1921-25), p. 350, entry for "Nāma" (retrieved 2007-06-20), states:
"nāma as metaphysical term is opposed to rūpa, & comprises the 4 immaterial factors of an individual (arūpino khandhā, viz. vedanā saññā sankhāra viññāṇa...). These as the noëtic principle comb[ine]d with the material principle make up the individual as it is distinguished by 'name & body' from other individuals. Thus nāmarūpa= individuality, individual being. These two are inseparable...."
This question and answer refers to the doctrine of dependent-arising (paticca-samuppada). Where rebirth-consciousness (pati-sandhi-vinnana) does not arise there is no establishment of an individual (mind-and-body, namarupa) in a realm of existence, nor the consequent appearance of old age and death and the other sufferings inherent in life.
