3)第三釋
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。
api khalv evam uktam āyuṣmatā ānandena ghoṣilasya gṛhapater / anyo ca gṛhapate cakṣurdhātur anyo rūpadhātur anyaś cakṣurvijñānadhātuḥ /
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。
sukhavedanīyaṃ gṛhapate (DhskD 9r10) dvayaṃ pratītya vijñānasyotpādo bhavati / trayāṇāṃ sannipātāt* sparśaḥ / tat khalu sukhavedanīyaṃ sparśaṃ pratītyotpadyate sukhā vedanā / anya eva yāvad /
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。
duḥkhavedanīyaṃ gṛhapate dvayaṃ pratītya (DhskD 9v1) vijñānasyotpādo bhavati / trayāṇāṃ sannipātāt* sparśaḥ duḥkhavedanīyaḥ / tat khalu duḥkhavedanīyaṃ sparśaṃ pratītyotpadyate duḥkhā vedanā / anya eva yāvad /
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。
aduḥkhāsukhavedanīyaṃ gṛhapate dvayaṃ pratītya vijñānasyotpādo (DhskD 9v2) bhavati / trayāṇāṃ sannipātaḥ sparśaḥ aduḥkhāsukhavedanīyaḥ / tat khalv aduḥkhāsukhavedanīyaṃ sparśaṃ pratītyotpadyate aduḥkhāsukhā vedanā /
餘五三界，廣說亦爾，是名觸緣受。
anya eva gṛhapate śrotraghrāṇajihvākāyamanodhātur anyo dharmadhātur (DhskD 9v3) anyo manovijñānadhātuḥ / sukhavedanīyaṃ gṛhapate dvayaṃ pratītya vistareṇa yathā pūrvoktaṃ / tad ucyate sparśapratyayā vedanā /
[參考]雜阿含460經
瞿師羅長者詣尊者阿難所，禮尊者阿難足，退坐一面，白尊者阿難：所說種種界。云何為種種界？尊者阿難告瞿師羅長者：眼界異、色界異喜處，二因緣生識，三事和合生觸，又喜觸因緣生樂受。如是耳、鼻、舌、身、意、法，亦如是說。復次，長者！有異眼界、異色界憂處，二因緣生識，三事和合生苦觸，彼苦觸因緣生苦受。如是耳、鼻、舌、身、意、法，亦如是說。復次，長者！異眼界、異色界捨處，二因緣生識，三事和合生不苦不樂觸，不苦不樂觸因緣生不苦不樂受。如是耳、鼻、舌、身、意、法，亦如是說。
4)第四釋
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。
api khalv evam uktaṃ bhagavatā mahānidānaparyāyesmin vyākaraṇe āyuṣmate ānandāya / (DhskD 9v4) asti pratyayam ānanda vedanā vistareṇa yāvac /
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！
cakṣuḥsaṃsparśaś ced ānanda nābhaviṣyad api nu cakṣuḥsaṃsparśapratyayam adhyātmam utpadyeta sukhaṃ vā duḥkhaṃ vā aduḥkhāsukhaṃ vā / no bhadanta /
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！
evaṃ śrotraghrāṇajihvākāyamahaḥsaṃsparśaḥ (DhskD 9v5) ced ānanda nābhaviṣyad api nu manaḥsaṃsparśapratyayam adhyātmaṃ utpadyeta veditaṃ sukhaṃ vā duḥkhaṃ vā aduḥkhāsukhaṃ vā / no bhadanta /
若全無觸，為可施設有諸受不？不也！世尊！
sarvaśo vā ānanda sparśe asati (DhskD 9v6) vedanā prajñāyeta / no bhadanta /
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。
tasmād dhy ānandaitan nidānaṃ vistareṇa yāvad / idaṃ mayā yad uktam idaṃ tat pratyuktaṃ //
[參考]中阿含97大因經
阿難！若有問者：覺有緣耶？當如是答：覺亦有緣。
若有問者：覺有何緣？當如是答：緣更樂也。當知所謂緣更樂有覺。
阿難！若無有眼更樂，各各無眼更樂者，設使離眼更樂，當有緣眼更樂生樂覺、苦覺、不苦不樂覺耶？答曰：無也。
阿難！若無耳、鼻、舌、身、意更樂，各各無意更樂者。設使離意更樂，當有緣意更樂生樂覺、苦覺、不苦不樂覺耶？答曰：無也。
阿難！是故當知是覺因、覺習、覺本、覺緣者，謂此更樂也。所以者何？緣更樂故則有覺。
