In the next sentences of the sutta the terms aniccasa~n~na and
asubhasa~n~na will be used, and their translation as "perception" can
be confusing.
Vi~n~nana, phassa, and even sa'nkharaa with vedana can also be seen as
aspects of 'perception' process.
We can place a footnote:
2. Apperception (sa~n~naa): The mental process of discrimination and
categorization of the perceived information, resulting in its
labeling. For example, the process in which the color of the perceived
visible object is designated as 'blue', 'yellow', 'red'.
For example, when a person in love sees everywhere his beloved, he
does not 'perceive' her. Rather he 'apperceives' anybody remotely
similar as the girl of his dreams.
Similarly the yogin, practicing asubhasa~n~naa, does not 'perceive'
the absence of beauty. Rather he 'apperceives' the absence of beauty,
being 'tuned' to this theme.
