Ahetuka Cittas which are Unknown in Daily Life - Panca-dvaravajjana-citta
One type of ahetuka kiriyācitta is the 'five-door-adverting-
consciousness', in Pāli: pañca-dvārāvajjana-citta. When an object
impinges on one of the five senses, there has to be a citta which adverts or
turns towards the object through that sense-door. When visible object
impinges on the eyesense, there has to be the adverting-consciousness which
adverts to visible object through the eye-door, the eye-door-adverting-
consciousness (cakkhu-dvārāvajjana-citta; ''cakkhu'' means ''eye''), before
there can be seeing-consciousness (cakkhu-viññāna). When sound impinges
on the earsense, the ear-door-adverting-consciousness (sota- dvārāvajjana-
citta; ''sota'' means ''ear'') has to advert to the sound through the ear-door
before there can be hearing-consciousness (sota-viiññāna). The pañca-
dvārāvajjana-citta merely turns towards the object which impinges on one of
the five senses. It turns, for example, towards the visible object or sound
which impinges on the corresponding sense-organ, but it does not see or
hear. The pañca-dvārāvajjana-citta is an ahetuka kiriyācitta, it arises without
hetu (root); there is not yet like or dislike when this citta arises. The pañca-
dvārāvajjana-citta is succeeded by one of the dvi-pañca viññānas, which is
vipākacitta.
Each citta which arises in the process of cittas experiencing an object has its
own function.
The cittas which experience an object through one of the sense-doors do not
know anything else but that object. When one, for example, is reading, the
citta which sees experience only visible object and it does not know the
meaning of the letters. After the eye-door process has been completed visible
object is experienced through the mind-door and then there can be other
mind-door processes of cittas which know the meaning of what has been
written and which think about it. Thus, there are processes of cittas which
experience an object through one of the senses and processes of cittas which
experience an object through the mind-door.
