俱舍論記 15.142

15.142

「若爾便與至名為善業」者，難。若於下地亦有善業能感捨受，便與前文所說相違，謂說善業始從欲界至第三定名順樂受。又與前文所說相違，得可愛果名為善業。捨非可愛，善如何感？

Regarding "If so, then it contradicts ... is called wholesome karma," this is an objection. If in the lower stages there is also wholesome karma that can bring about equanimity feeling, then it contradicts what was stated in the previous text—namely, stating that wholesome karma, starting from the desire realm up to the third dhyāna, is called conducive to pleasant feeling. Furthermore, it contradicts what was stated in the previous text: that which attains a desirable result is called wholesome karma. Equanimity is not [specifically] desirable; how could wholesome [karma] bring it about?
