相應部36相應10經/觸為根本經(受相應/處篇/修多羅)(莊春江譯)
「
比丘們！這三受是觸生的，觸為根本，觸為因，觸
為緣，哪三個？樂受、苦受、不苦不樂受。
比丘們！
緣於能被感受為樂之
觸，樂受生起，就以那個能被感受為樂之觸的
滅，凡對應那個所感受的：緣於能被感受為樂之觸生起的樂受，它被滅，它被平息。
比丘們！緣於能被感受為苦之觸，苦受生起，就以那個能被感受為苦之觸的滅，凡對應那個所感受的：緣於能被感受為苦之觸生起的苦受，它被滅，它被平息。
比丘們！緣於能被感受為不苦不樂之觸，不苦不樂受生起，就以那個能被感受為不苦不樂之觸的滅，凡對應那個所感受的：緣於能被感受為不苦不樂之觸生起的不苦不樂受，它被滅，它被平息。
比丘們！猶如從兩塊柴的磨擦、結合，熱被產生，火生起。就從那兩塊柴的分離分置，凡對應那個的熱，它被滅，它被平息[SN.12.62, SN.48.39]。同樣的，比丘們！這三受是觸生的，觸為根本，觸為因，觸為緣，緣於對應那個之觸，對應那個的諸受生起，以對應那個之觸的滅，對應那個的諸受被滅。」
有偈品第一，其
攝頌：
「定、樂與捨斷，深淵與應該被看作，
箭與生病，無常、根源於觸。」
