論：應說此意至善業果故。

Treatise: It should be said that this manas [is conjoined with four feelings, excepting only suffering, because in the three realms and nine bhūmis, wherever it is born, it cognizes the maturation of karma that belongs to that bhūmi, which is the fruit of karma conjoined with superior feelings of that bhūmi].
