6 The relation of indriya (faculty of control) is threefold:
i The five sensitive organs (pasàda-råpas) are related to
pa¤ca-vi¤¤àõa (eye-consciousness, ear-consciousness,
etc.), by way of indriya condition.
ii Jãvita-råpa (material vitality) is related to kammaja-råpas
by way of indriya condition.
iii. Mental indriyas (immaterial controlling factors) are
related to co-nascent mind and matter by way of indriya
condition.
7 The relation of vippayutta (dissociation) is threefold:
i At the moment of conception, the heart-base is related
to the rebirth-consciousness and its concomitants by
way of sahajàta-vippayutta condition. Citta and cetasikas
are also similarly related to co-nascent matter.
ii Subsequent cittas and cetasikas are related to preceeding
and previous corporeal groups (heart-bases and sensebases)
by way of pacchàjàta-vippayutta condition.
iii The six bases during life are related to the seven
vi¤¤àõa-dhàtus (i.e. all cittas) by way of purejàtavippayutta
condition.

are each fivefold:
The relations of sahajàta (co-nascence), purejàta (prenascence),
pacchàjàta (post nascence), àhàra (nutriment),
and råpa-jivthindriya (material vitality) also serve as
the relations for atthi and avigata. Atthi and avigata are
more or less identical.
