SN46:132-136"Bhikkhus, just as whatever great rivers there are— that is, the Ganges, the Yamuna, the Aciravati, the Sarabhū, the Mahī— all slant, slope, and incline towards the east,
SN46:137-142 … just as whatever great rivers there are— that is, the Ganges, the Yamuna, the Aciravati, the Sarabhū, the Mahī— all slant, slope, and incline towards the ocean,

so too a bhikkhu who develops and cultivates the seven factors of enlightenment slants, slopes, and inclines towards Nibbāna."

"And how does he do so?

"Here, bhikkhus, a bhikkhu develops the enlightenment factor of mindfulness,
- which has as its final goal the removal of lust, the removal of hatred, the removal of delusion;
- which has the Deathless as its ground, the Deathless as its destination, the Deathless as its final goal;
- which slants, slopes, and inclines towards Nibbāna.

He develops the enlightenment factor of discrimination of states,
- which has as its final goal the removal of lust, the removal of hatred, the removal of delusion;
- which has the Deathless as its ground, the Deathless as its destination, the Deathless as its final goal;
- which slants, slopes, and inclines towards Nibbāna.

He develops the enlightenment factor of energy,
- which has as its final goal the removal of lust, the removal of hatred, the removal of delusion;
- which has the Deathless as its ground, the Deathless as its destination, the Deathless as its final goal;
- which slants, slopes, and inclines towards Nibbāna.

He develops the enlightenment factor of rapture,
- which has as its final goal the removal of lust, the removal of hatred, the removal of delusion;
- which has the Deathless as its ground, the Deathless as its destination, the Deathless as its final goal;
- which slants, slopes, and inclines towards Nibbāna.

He develops the enlightenment factor of tranquillity,
- which has as its final goal the removal of lust, the removal of hatred, the removal of delusion;
- which has the Deathless as its ground, the Deathless as its destination, the Deathless as its final goal;
- which slants, slopes, and inclines towards Nibbāna.

He develops the enlightenment factor of concentration,
- which has as its final goal the removal of lust, the removal of hatred, the removal of delusion;

He develops the enlightenment factor of equanimity,
- which has as its final goal the removal of lust, the removal of hatred, the removal of delusion;
- which has the Deathless as its ground, the Deathless as its destination, the Deathless as its final goal
- which slants, slopes, and inclines towards Nibbāna.

It is in this way that a bhikkhu slants, slopes, and inclines towards Nibbāna." [n.121] I follow the method of Ee, which ends with 175. Apparently three repetitions of the entire series should be understood for each of the three ways of describing the enlightenment factors. Here, the other two methods—"the Deathless as its ground" series and the "slants towards Nibbāna" series— are explicit only in the last sutta but, in this digital version, have been added here.
