If the seeing-consciousness is akusala vipāka, the sampaticchana-citta
(receiving-consciousness) is also akusala vipāka; if the seeing-consciousness
is kusala vipāka, the sampaticchana-citta is also kusala vipāka. Thus, there
are two types of sampaticchana-citta: one is akusala vipāka and one is
kusala vipāka. Sampaticchana-citta: is ahetuka vipakā; there are no akusala
hetus (unwholesome roots) or sobhana hetus (beautiful roots) arising with
this type of citta. Sampaticchana-citta succeeds seeing-consciousness;
seeing-consciousness is a condition for the arising of sampaticchana-citta.
Likewise, when there is hearing-consciousness which hears sound,
sampaticchana-citta succeeds hearing-consciousness. It is the same with
regard to the other sense-doors.
Sampaticchana-citta always arises with upekkhā (indifferent feeling), no
matter whether the sampaticchana-citta is akusala vipāka or kusala vipāka.
