''A hard thing there is, O King, which the Blessed One has done.''
''And what is that?''
''The fixing of all those mental conditions which depend on one organ of
sense, telling us that such is contact, such is feeling, such is saññā
(perception), such is volition and such is citta.''
''Give me an illustration.''
''Suppose, O King, a man were to wade down into the sea,
and taking some water in the palm of his hand,
were to taste it with his tongue. Would he distinguish
whether it were water from the Ganges, or from the Jamuna,
or from the Aciravatiํ, or from the Sarabhu, or from the Mahํ?''
''More difficult than that, great King, is it to have distinguished
between the mental conditions which follow on the exercise
of any one of the organs of sense!''
Citta and cetasika are paramattha dhammas (absolute realities) which each
have their own unchangeable characteristic. These characteristics can be
experienced, regardless how one names them. Paramattha dhammas are not
words or concepts, they are realities. Pleasant feeling and unpleasant feeling
are real; their characteristics can be experienced without having to call them
''pleasant feeling'' or ''unpleasant feeling''. Aversion is real; it can be
experienced when it presents itself.
