What four? A mendicant would meditate observing an aspect of the body—keen, aware, and mindful, rid of covetousness and displeasure for the world. Or they’d meditate observing an aspect of feelings … or mind … or principles—keen, aware, and mindful, rid of covetousness and displeasure for the world. The four kinds of mindfulness meditation are the path to convergence. They are in order to purify sentient beings, to get past sorrow and crying, to make an end of pain and sadness, to discover the system, and to realize extinguishment.”

That is what the divinity Sahampati said. Then he went on to say:

“The compassionate one, <j>who sees the ending of rebirth, understands the path to convergence. By this path people crossed over before, will cross, and are crossing.”
