俱舍論疏 22.109

22.109

論「又彼所說至應知亦爾」，此破易脫生樂因。於初易肩分位之時有實樂生，若異此者，初易之後應漸樂增，以前重苦後漸微故。易脫威儀生於樂者，亦准此釋。

On the Śāstra's 'Furthermore, what they say [...] should be understood likewise': This refutes [the view that] shifting [a burden] is the cause of producing pleasure. At the state of initial shifting to the shoulder, real pleasure is produced; if it were otherwise, after the initial shift pleasure should gradually increase, because the previous heavy suffering would gradually lessen afterward. That shifting deportment produces pleasure is also explained by analogy with this.
