Nāma-rūpa: lit. 'name and form': 'mind-and-body', mentality and materiality. It is the 4th link in the dependent origination see: paticcasamuppāda 3, 4 where it is conditioned by consciousness, and on its part is the condition of the sixfold sense-source. In two texts D. 14, 15, which contain variations of the dependent origination, the mutual conditioning of consciousness and mind-and-body is described see also S. XII, 67, and the latter is said to be a condition of sense-contact phassa; so also in Sn. 872.
The third of the seven purifications see: visuddhi the purification of views, is defined in Vis.M XVIII as the;correct seeing of mind-and-body,; and various methods for the discernment of mind-and-body by way of insight-meditation vipassanā are given there. In this context, 'mind' nāma comprises all four mental groups, including consciousness. - See nāma
In five-group-existence pañca-vokāra-bhava, mind-and body are inseparable and interdependent; and this has been illustrated by comparing them with two sheaves of reeds propped against each other: when one falls the other will fall, too; and with a blind man with stout legs, carrying on his shoulders a lame cripple with keen eye-sight: only by mutual assistance can they move about efficiently see: Vis.M XVIII, 32ff. On their mutual dependence, see also paticca-samuppāda 3.
With regard to the impersonality and dependent nature of mind and materiality it is said:
Sound is not a thing that dwells inside the conch-shell and comes out from time to time, but due to both, the conch-shell and the man that blows it, sound comes to arise: Just so, due to the presence of vitality, heat and consciousness, this body may execute the acts of going, standing, sitting and lying down, and the 5 sense-organs and the mind may perform their various functions; D. 23.
Just as a wooden puppet though unsubstantial, lifeless and inactive may by means of pulling strings be made to move about, stand up, and appear full of life and activity; just so are mind and body, as such, something empty, lifeless and inactive; but by means of their mutual working together, this mental and bodily combination may move about, stand up, and appear full of life and activity.
