Slanting East
“Mendicants, the Ganges River slants, slopes, and inclines to the east. In the same way, a mendicant who develops and cultivates the noble eightfold path slants, slopes, and inclines to extinguishment. And how does a mendicant who develops the noble eightfold path slant, slope, and incline to extinguishment? It’s when a mendicant develops right view, right purpose, right speech, right action, right livelihood, right effort, right mindfulness, and right immersion, which culminate in the removal of greed, hate, and delusion. That’s how a mendicant who develops and cultivates the noble eightfold path slants, slopes, and inclines to extinguishment.”
