Samyuktagama (Sanskrit fragments) 612.5-6

612.5

佛說此經已，諸比丘聞佛所說，歡喜奉行。

When the Buddha had spoken this sūtra, the bhikṣus, having heard what the Buddha had said, rejoiced and respectfully put it into practice.

“You should know that the Tathāgata’s teachings are measureless and limitless. Their bodies of names, lines, and themes are also measureless and without any final end. That teaching is the four abodes of mindfulness. What are the four? They are the mindful abode of body … feelings … mind … the mindful abode of principles. (7.11 adds this conclusion:) Therefore, monks, cultivation of these four abodes of mindfulness produces motivation. With energy, technique, right mindfulness, and right knowledge, you should train yourselves.”

After the Buddha spoke this sūtra, the monks who heard what the Buddha taught rejoiced and approved.

612.6

一切四念處經，皆以此總句，所謂「是故，比丘！於四念處修習，起增上欲，精勤方便，正念正智，應當學。」

All the sūtras on the four smṛtyupasthānas conclude with this general phrasing: 'Therefore, bhikṣus, you should cultivate the four smṛtyupasthānas, arouse superior desire, exert diligent effort and skillful means, have right mindfulness and right awareness, and so you should train.'
