成唯識論演祕 5.132

5.132

證有遍行，即彼論云，如經中說，苦於此作意等。又說由彼所生作意正起，如是所生眼等識生，如經說有六觸身；又說眼、色為緣，能起眼識，如是三法聚集合，故能有所觸；又說觸為受緣，如經說有六受身；又說受為愛緣，如經說有六想身；又說如其所想而起言議，如經說有六思身；又說當知我今六觸處，即前世思所造故業。

To prove the existence of the omnipresent factors, that treatise states: As the sūtra says, "...attention to this suffering," and so forth. It also says that with attention generated by that properly arising, eye-consciousness and so forth arise accordingly; as the sūtra says, there are six classes of contact; it also says that with eye and form as conditions, eye-consciousness can arise, and the gathering and harmonious union of these three phenomena can produce contact; it also says that contact is the condition for sensation, as the sūtra says there are six classes of sensation; it also says that sensation is the condition for craving, as the sūtra says there are six classes of perception; it also says that as one perceives, one produces verbal expression, as the sūtra says there are six classes of volition; it also says: You should know that my present six sense-fields of contact are the past karma created by volition in previous lives.
