The last two, i.e., sampañichana-citta and santãraõa-citta,
represent two connecting stages in the process of cognition
(awareness of an object).
For example, when a visual object appears in the eye, a series
of consciousness has to arise and dissolve in order to see the
object. First pa¤ca-dvàràvajjana (five-door advertence) adverts the
consciousness towards the object. Then cakkhu-viññàõa (eyeconsciousness)
makes the sense-impression. Then sampañichana
(receptive consciousness) receives the sense-impression. Then
santãraõa (investigating consciousness) investigates the senseimpression.
Then vottappana (determinng consciosness) also
known as mano-dvàràvajjana (mind-door advertence) determines
the sense-impression whether it is good or bad. We are aware of
the object roughly at this stage.
Similarly, when an audible voice strikes the eardrum, a series
of consciousness, i.e., pa¤ca-dvàràvajjana, sotaviññàõa, sampañichana,
santàraõa, mano-dvàràvajjana, etc., has to arise and dissolve before
we can hear the voice.
Thus sampañichana-citta, santàraõa citta together with pa¤ca
dvàràvajjana citta and mano-dvàràvajjana citta are essential for
cognition of the senses at the five sense-doors (eye, ear, nose,
tongue and body).
Ahetuka Kusala Vipàka Cittas
This class comprises eight cittas whose symbols and names are
similar to those of akusala-vipàka cittas we have just described above.
