俱舍論記 5.90

5.90

「有餘師言至心有根身」者，第二有餘經部師言：如生無色界，色久時斷，如何於後色復得生？彼生定應由心中色種子生，非過去色生。此即舉例。如是出定心亦應然，由定內有五根身中有心種子，生出定心，非由過去定前心起。故彼經部中先代諸軌範師咸言：心、身二法互為種子。

On [the text reading]: "Other masters say ... mind has the physical body with faculties": This is the second [view, in which] other Sautrāntika masters say: Just as when one is born into the formless realm, matter is severed for a long time, how can matter arise again afterward? Its arising must certainly be produced by the seeds of matter within the mind, not produced from past matter. This is citing an example. Likewise, the mind emerging from the absorption should also be so: from the seeds of mind within the physical body possessing the five faculties during the absorption, the emerging mind is produced, not arising from the past mind prior to the absorption. Therefore, the earlier masters of that Sautrāntika [tradition] all stated: the two dharmas of mind and body serve as seeds for each other.
