The Discourse on the Seed
150.
"Just as, monks, whatever seed-plants and growing plants attain growth, increase, and expansion, all of them do so in dependence on earth, established upon earth, thus these seed-plants and growing plants attain growth, increase, and expansion;
so too, monks, a monk, based upon morality, established upon morality, developing the noble eightfold path, cultivating the noble eightfold path, attains growth, increase, and expansion in mental states.
And how, monks, does a monk, based upon morality, established upon morality, developing the noble eightfold path, cultivating the noble eightfold path, attain growth, increase, and expansion in mental states?
Here, monks, a monk develops right view, based upon seclusion, etc.
he develops right concentration, based upon seclusion, based upon dispassion, based upon cessation, maturing in release, etc.
Thus, monks, a monk, based upon morality, established upon morality, developing the noble eightfold path, cultivating the noble eightfold path, attains growth, increase, and expansion in mental states."
