212 The Abhidharma
combination of just eighty-one classes of dharma. Indeed, accord-
ing to an old image, the mind is far more complex, subtle, and
varied than any painting? Moreover the arising of dharmas is
seamless and the difficulty of distinguishing different kinds of
dharma in actual experience is compared to tasting the waters
of the sea and knowing that certain water comes from one river
and certain water from another river.^8
The term citta or consciousness is used in two senses: (I) as a
name for one of the eighty-one classes of dharma, namely the
bare phenomenon of consciousness; ( 2) as a term for a given com-
bination of consciousness and its associated mental factors. Con-
sciousness in this second sense might be compared to a hand:
the hand excluding the fingers is like the bare dharma of con~
sciousness (the' first sense), while the fingers are like the various
associated mental factors; a given arising of consciousness is
thus analogous to consciousness experiencing or picking up an:d
handling a particular object by means of the associated mental
factors. The flow of consciousness involves the mind picking up
and putting down successive objects by means of successive sets
of associated mental factors. In fact an old image from the siltras
compares the mind to a monkey swinging quickly through the
trees in the forest: as soon as it lets go of one branch it grasps
another.^9
Although there is a total of fifty-two types of associated
mental factor, only certain combinations of these are possible;
for example it is impossible for the mental factors of greed and
aversion to arise together in the same moment of consciousness
for the simple reason that it is not possible to want something
and not want it in the same moment-this does not, of course,
mean that we cannot want something one moment and not want
it the next. As I have already mentioned, for the Theravadins
the simplest kind of consciousness that can occur involves seven
associated mental factors. More complex consciousnesses involve
up to a maximum of thirty-six types of associated mental factor.
The Theravadin Abhidharma tabulates a system of eighty-nine
basic classes of consciousness based on possible combinations
of consciousness and associated mental factors. Normal human
