Vipàka Niyàma
‘Niyàma’ means ‘law’. As vipàka cittas are the resultants of kammas
(actions), they arise in vãthis regularly according to the kammas
just as the image appears in the mirror in accordance with the
person in front of the mirror.
Now one comes across unpleasant objects such as a decaying
carcass, night-soil, etc., on account of akusala kamma (unwholesome
action). So at such moments, akusala vipàka cittas—namely,
cakkhu-vi¤¤àõa, sampañicchana, santàraõa and tadàlambaõa arise
in the vãthi.
When one comes across fairly good objects, kusala vipàka
cittas—namely, cakkhu-vi¤¤àõa, sampañicchana, upekkhà-santàraõa
and upekkhà-tadàlambaõa arise in vãthis. When the object is every
good, somanassa-sanàraõa and somanassa-tadàlambaõa arise instead
of the upekkhà-ones.
Kusala and akusala-javanas do not occur regularly as vipàka
cittas. Yoniso-manasikàra (wise reflection) leads to the arising of
kusala-javanas whereas ayoniso-manasikàra (unwise reflection)
gives rise to akusala-javanas.
Frequency of Kàma-javanas
Normally kàma-javana arises seven times in a vãthi. But in young
babies and unconscious person, the hadaya-vatthu is weak and,
accordingly, kàma-javana arises six or five times in a vãthi.
In maranàsanna vãthi, which occurs at the time of dying, kàmajavana
occurs only five times.
In paccavekkhaõa-vãthis (retrospective cognitive process), the
person is examining the jhàna-factors very rapidly and so kàmajavana
occurs only four or five times per vãthi.
In upacàra-samàdhi javana, kàma-javana occurs four times as
parikamma, upacàra, anuloma and gotrabhu in persons of slow
