俱舍論疏 30.39

30.39

論「依如是義至便壞善業子」，依前長行之義說此頌也。如虎銜子，不急不緩。若急說有命者，即執真我為有，為我見牙傷；若緩說無命者，撥俗我為無，便壞善業子，所以不答。

On the Śāstra's statement: "Based on this meaning [...] it harms the cub of good karma": Based on the meaning of the preceding prose, this verse is spoken. It is like a tigress holding her cub in her mouth, neither too tightly nor too loosely. If she is too tight in saying there is a soul, they will cling to a real self as existing, and be injured by the fangs of the view of self; if she is too loose in saying there is no soul, they will deny the conventional self as non-existent, and thus harm the cub of good karma; therefore He did not answer.
