俱舍論疏 30.85

30.85

論「此難非理至有因果性故」，論主通也。前心、後心一相續，有因果義，所以後心憶前心境。天授、祠授是異相續，無因果故，不相憶也。

On the Śāstra's: "This objection is unreasonable ... because of having the nature of cause and effect": The author of the Śāstra resolves it. The earlier mind and the later mind belong to one continuum and have the sense of cause and effect; therefore, the later mind remembers the object of the earlier mind. Devadatta and Yajñadatta are different continua, and lacking cause and effect, they do not remember each other's [objects].
