17.151

「約異熟果至無間隔義」者，答中有二，此即初說。定受彼果，無餘業生為間隔故，立無間名。此即約法以明。

"In terms of the fruit of ripening: Up to: The meaning of without interval": There are two within the answer; this is the first statement. Because one determinately experiences that fruit without other karma-birth intervening as an interval, the name ānantarya (uninterrupted/immediate) is established. This clarifies it in terms of dharma.
