Function of Javana - Cittas which perform the function of javana

There are fifty-five kinds of citta which can perform the function of

javana. Twelve akusala cittas (eight lobha-mūla-cittas, two dosa-mūla-

cittas and two moha-mūla-cittas), eight kāmāvacara kusala cittas, which

are called mahā-kusala cittas, eight mahā-kiriyācittas of the arahat

(kiriyācittas which are not ahetuka, but accompanied by sobhana hetus). The

arahat has mahā-kiriyācittas instead of mahā-kusala cittas since he does not

accumulate any more kamma. Mahā-kiriyācittas are of the sensuous plane of

consciousness; they are not jhānacittas or lokuttara cittas. Arahats also have

kāmāvacara citta; they see, hear or think of objects experienced through

the senses. However, on account of what is experienced no kusala cittas or

akusala cittas arise.

For the arahat there is also an ahetuka kiriyācitta performing the function

of javana, which may arise when he smiles : the hasituppāda-citta

Those who attain rūpa-jhāna (fine material jhāna) can have five types of

rūpāvacara kusala cittas performing the function of javana, since there are

five stages of rūpa-jhāna. Arahats who attain rūpa-jhāna can have five types

of rūpāvacara kiriyācittas which perform the function of javana.

For those who attain arūpa-jhāna (immaterial jhāna) there can be four types

of arūpāvacara kusala cittas performing the function of javana, since

there are four stages of arūpa-jhāna Arahats who attain arūpa-jhāna can have

four types of arūpāvacara kiriyācittas performing the function of javana.

Those who directly experience nibbāna have lokuttara cittas. There are eight lokuttara cittas, four of which are magga-cittas ('path-consciousness', 'magga' means path) and four of which are lokuttara vipākacittas, called phala-cittas (‘fruit-consciousness', 'phala' means fruit. Vipākacittas of other of consciousness cannot perform the function of javana) Thus, all eight lokuttara cittas perform the function of javana.
