IX. Ganges Repetition Series

77 (1)–88 (12) 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 7 factors of enlightenment slants, slopes, and inclines towards Nibbāna.

And how, Bhikkhus, does a Bhikkhu develop and cultivate the 7 factors of enlightenment so that he slants, slopes, and inclines towards Nibbāna?

Here, Bhikkhus, a Bhikkhu develops the enlightenment factor of mindfulness … he develops the enlightenment factor of equanimity, which is based upon seclusion, dispassion, and cessation, maturing in release.

It is in this way, Bhikkhus, that a Bhikkhu develops and cultivates the 7 factors of enlightenment so that he slants, slopes, and inclines towards Nibbāna.

(The remaining Suttas of this vagga are to be similarly elaborated parallel to 45:92–102.)

6 about slanting to the east
And 6 about slanting to the ocean.
These 2 sixes make up twelve:
Thus the subchapter is recited.
