1-12.
The Discourse on the Ganges River and so on
258-269. "Just as, monks, the river Ganges slants towards the east, slopes towards the east, inclines towards the east; just so, monks, a monk developing the seven factors of enlightenment, cultivating the seven factors of enlightenment, slants towards Nibbāna, slopes towards Nibbāna, inclines towards Nibbāna. And how, monks, does a monk developing the seven factors of enlightenment, cultivating the seven factors of enlightenment, slant towards Nibbāna, slope towards Nibbāna, incline towards Nibbāna? Here, monks, a monk develops the enlightenment factor of mindfulness, etc. he develops the enlightenment factor of equanimity, based upon seclusion, based upon dispassion, based upon cessation, maturing in release, etc. Thus, monks, a monk developing the seven factors of enlightenment, cultivating the seven factors of enlightenment, slants towards Nibbāna, slopes towards Nibbāna, inclines towards Nibbāna."
