Nirvikalpaka is the word for a kind of basic
non-conceptual consciousness produced only by the action of the senses in
various schools of Indian philosophy, including the Buddhists, the Nyayas, and
the Prabhakara school of Mimamsa.
According to these schools, an awareness is deemed to be
real if the senses that produce it are free of flaws.
However, the mind's activity might cause it to be
misconstrued or misread.
This notion has significant implications for mistake
theories, which attempt to explain how erroneous judgements might occur.
The schools that subscribed to this philosophy ascribed
mistake to mental activity.
