17.64

異地二或三者，若是有漏業，以異地法為二果，謂士用、增上。若無漏業，以異地法為三果，於前二果更加等流，不墮界故，有等流果。

Regarding "of a different plane, two or three": if it is contaminated karma, it takes phenomena of a different plane as two fruits, namely personal endeavor and sovereignty. If it is uncontaminated karma, it takes phenomena of a different plane as three fruits: to the previous two fruits, outflow is added; because it does not fall within the realms, it has the outflow fruit.
