Buddhism inherited many of the traditional elements of the Aryans. — Hajime Nakamura, Indian Buddhism
Many technical words used by the Buddha stem from Brahmanism, especially, from the Upanishads in terms of key important notions. The Buddha, himself, was not keen on a metaphysical speculative understanding of salvation (i.e., deliverance from suffering). He sided with the ancient tradition of yoga—yoga, that is, in the sense of a fundamental praxis that penetrates throgh the cosmic veil of illusion by which pure Mind restores itself to itself. This veil can be likened to an interference based texturing of Mind that we behold as our phenomenal world in which non-textured Mind is nowhere detected; having lost its fundamental bearings. This is what the Buddha’s yoga seeks to restore, as is were, the yoking of the absolute with itself.
One of the major Brahmanist notions that found major importance in Buddhism is nama-rupa, often translated as “name and form”. However, this is a woefully inaccurate translation, for it has a wider latitude of meaning. It is more akin to the idea of subject and object, or individuation, whereby consciousness enters into a kind of cosmic self-repulsion—reacting against itself becoming thus pluralized. Nama-rupa can also be equated with maya as something that is an artifact, that is, something constructed rather than primary (svabhava).
Turning to the Buddhas twelve and tenfold nidanas (i.e., sunderings) in which nama-rupa appears, the coupling of nama-rupa and consciousness (vijnana) is the beginning of the fall of consciousness into illusion by which it becomes bound to suffering. This coupling really signifies the pluralization of consciousness becoming thus a corporeal entity.
In this down-going (nidana), consciousness becomes split into ideas or essences (nama), and their forms (rupa), or more precisely, aetheric constructs. Through nama-rupa in which consciousness is tied to the corporeal body, eventually, consciousness succumbs to aging and death according to the twelve (or ten) nidana theory of the Buddha.
In death, mind (citta) which is not yet consciousness-ized [sic] is submerged in its own self-begotten ignorance (the first of the twelve nidanas) from which, again, it emerges to specifically link with another nama-rupa condition. This is rebirth—what Hindus fear the most—which Westerners do not believe; who believe death is utter finality.
This unfortunate state of being is otherwise called “samsara” in which the individual is an admixture of immortal and the mortal; mixed together like gold dust and brass dust. There is yet no prajna or differentiating wisdom for the individual whereby the immortal is distinguished from the mortal this being an important step in the Buddha’s yoga. Said another way, in the corporalized nama-rupa condition, mind conceals its own original luminous nature. It is in a deep sleep from which it is almost impossible to awaken (bodhi).
Being bound in a condition of non-totality; facing death, it comes, therefore, as a great joy for the Buddhist yogi to enter samadhi experiencing a lightning-instant of luminous Mind which has been roused from its sleep. For the first time there is the experience of freedom from nama-rupa.
Here really commences the work of yoga, that is, the work of continually yoking with the vital power of free Mind. Rightly, yoga is a path which is moving away from nama-rupa which leads to nirvana-dhatu (nirvana realm); nirvana being beyond the three lokas comprising samsara consisting of the Desire World, the Form World, and the Formless World.
