答。領納相是受相。由此受故。領納種種淨不淨業。所得異熟。若清淨業。受樂異熟。不清淨業。受苦異熟。淨不淨業。受不苦不樂異熟。所以者何。由淨不淨業。感得異熟阿賴耶識。恒與捨受相應。唯此捨受。是實異熟體。苦樂兩受。從異熟生。故假說名異熟。

Answer: The characteristic of experiencing is the characteristic of sensation. Due to this sensation, one experiences the various maturation [results] obtained from pure and impure karma: if it is pure karma, one experiences pleasurable maturation; if it is impure karma, one experiences painful maturation; if it is pure-and-impure karma, one experiences neither-painful-nor-pleasurable maturation. Why is this? Through pure and impure karma, the maturation ālayavijñāna is induced, which is always associated with equanimous sensation. Only this equanimous sensation is the real substance of maturation. The two sensations of pain and pleasure are produced from maturation, and therefore are metaphorically called maturation.
