The River Ganges—Eastward, Etc.

“Bhikkhus, just as the river Ganges slants, slopes, and inclines towards the east, so too a bhikkhu who develops and cultivates the four establishments of mindfulness slants, slopes, and inclines towards Nibbāna.

“And how, bhikkhus, does a bhikkhu develop and cultivate the four establishments of mindfulness so that he slants, slopes, and inclines towards Nibbāna?

It is in this way, bhikkhus, that a bhikkhu develops and cultivates the four establishments of mindfulness so that he slants, slopes, and inclines towards Nibbāna.”
