4.145

二十、「樂俱行，除二，所餘」等者，《唯識》言：十樂、捨俱，受不與受共相應故，老死位中多分無樂及容捨故。十一苦俱，非受俱故。老死多苦，故說十一，其種子體依當位俱，如有支等。種與種俱，皆如理思。俱，謂俱有。

20. Regarding "Concomitant with pleasure, excluding two, the remainder," and so forth: the Weishi says: "Ten are concomitant with pleasure and equanimity, because feeling does not associate with feeling itself, and in the state of old age and death there is mostly no pleasure and it permits equanimity. Eleven are concomitant with pain, because it does not associate with feeling itself. Old age and death have much pain, so it mentions eleven." The essential nature of their seeds is concomitant according to their corresponding states, as in the existence-constituent and so forth. Seeds being concomitant with seeds should all be contemplated correctly. 'Concomitant' means co-existent.
