雜阿含298經
緣觸受者，云何為受？謂三受：苦受、樂受、不苦不樂受。
瑜伽師地論卷第九
樂受云何？謂順樂諸根、境界為緣，所生適悅受，受所攝。苦受云何？謂順苦二為緣，所生非適悅受，受所攝。不苦不樂受云何？謂順不苦不樂二為緣，所生非適悅非不適悅受，受所攝。欲界三，色界二，第四靜慮以上乃至非想非非想處唯有第三不苦不樂。此亦二種。謂觸種子所攝受種子受，及彼所生果受。

云何觸緣受？
1)謂眼及色為緣生眼識，三和合故生觸，觸為緣生受。乃至意及法為緣生意識，三和合故生觸，觸為緣故生受。是名觸緣受。
2)復次眼及色為緣生眼識，三和合故生觸，或順樂受、或順苦受、或順不苦不樂受，順樂受觸為緣生樂受、順苦受觸為緣生苦受、順不苦不樂受觸為緣生不苦不樂受。乃至意及法為緣生意識，三和合故生觸，或順樂受、或順苦受、或順不苦不樂受，順樂受觸為緣生樂受、順苦受觸為緣生苦受、順不苦不樂受觸為緣生不苦不樂受，是名觸緣受。
3)復次如契經說，尊者慶喜告瞿史羅長者言：眼界、色界、眼識界，自體各別，順樂受二為緣生眼識，三和合故生觸，名順樂受觸，此順樂受觸為緣生樂受。順苦受二為緣生眼識，三和合故生觸，名順苦受觸，此順苦受觸為緣生苦受。順不苦不樂受二為緣生眼識，三和合故生觸，名順不苦不樂受觸，此順不苦不樂受觸為緣生不苦不樂受。餘五三界，廣說亦爾，是名觸緣受。
4)復次《大因緣經》中尊者慶喜問佛：諸受為有緣不？佛言：有緣，此緣謂觸。廣說乃至若無眼觸，為有眼觸為緣，生內樂受苦受不苦不樂受不？不也。世尊！乃至若無意觸，為有意觸為緣，生內樂受苦受不苦不樂受不？不也。世尊！若全無觸，為可施設有諸受不？」不也。世尊！是故慶喜！諸受無不以觸為緣，是名觸緣受。如是諸受，觸為緣、觸為依、觸為建立故、起等起、生等生、聚集出現，故名觸緣受。
