Samyukta Āgama (292), Part Four

(4) Original text:复次。比丘思量观察正尽苦。究竟苦边。时思量彼触何因何集。何生何触。当知彼触六入处因。六入处集。六入处生。六入处触。彼六入处灭无余。则触灭。彼所乘六入处灭道迹。如实知。修习彼向次法。是名比丘向正尽苦。究竟苦边。

Explanation: The Buddha further instructed: Furthermore, a bhikṣu should deliberate and contemplate the complete cessation of suffering, reaching the ultimate end of suffering, and should then continue to deliberate and contemplate: upon what condition does contact arise, from the arising of what dharma does it come together, after the arising of what dharma is it brought forth, and after contacting what dharma is it born? At this time one should know that contact arises due to the condition of the six sense bases (ṣaḍāyatana); it appears through the coming together of the six sense bases; the arising of the six sense bases leads to the appearance of contact; and it is the contact of the six sense bases that causes contact to be produced. When the six sense bases cease without remainder, contact ceases. Bhikṣus should truly understand the path of the cessation of the six sense bases that they themselves practice, and cultivate the path-leading dharma and the secondary dharmas that tend toward the complete cessation of suffering. This is called a bhikṣu tending toward the complete cessation of suffering, able to reach the ultimate end of suffering.
