lit. 'indeterminate' - i.e. neither determined as karmically 'wholesome' nor as 'unwholesome' - are the karmically neutral, i.e. amoral, states of consciousness and mental factors.
They are either mere karma-results (vipāka), as e.g. all the sense perceptions and the mental factors associated therewith, or they are karmically independent functions (kiriya-citta), i.e. neither karmic nor karma-resultant.
