There are of course two sampañichana cittas and three santãraõa
cittas.
All the akusala-vipàka cittas and ahetuka kusala vipàka cittas,
being comparatively weak as they are not aware of the senses as
good or bad yet, are accompanied by neutral feeling; the exceptions
are that the two body kàyaviññàõa cittas are accompanied
by either painful or pleasant feeling and somanassa-santãraõa citta,
which arises when the sense is excellent, is accompanied by joy.
Ahetuka Kiriya Cittas
The three ahetuka kiriya cittas are given the following symbols
and names.
pañcadvà manodvà hasi

1 Upekkhà-sahagataü pañcadvàràvajjana-cittaü
five-door adverting consciousness accompanied by
indifference
2 Upekkhà-sahagataü manodvàràvajjana-cittaü
mind-door adverting consciousness accompanied by
indifference
3 Somanassa-sahagataü hasituppàda-cittaü
smile-producing consciousness accompanied by joy
The functions of the two avajjana-cittas, i.e., No. 1 and No. 2
above, in the processes of cognition have been described above.
If the sense-object appears at one of the five sense-doors, it is
pa¤ca-dvàràvajjana which adverts consciousness towards the sense.
