Nagas

“Bhikkhus, based upon the Himalayas, the king of mountains, the nagas nurture their bodies and acquire strength. When they have nurtured their bodies and acquired strength, they then enter the pools. From the pools they enter the lakes, then the streams, then the rivers, and finally they enter the ocean. There they achieve greatness and expansiveness of body. So too, bhikkhus, based upon virtue, established upon virtue, a bhikkhu develops and cultivates the Noble Eightfold Path, and thereby he achieves greatness and expansiveness in wholesome states.

“And how does a bhikkhu do so? Here, bhikkhus, a bhikkhu develops right view … right concentration, which is based upon seclusion, dispassion, and cessation, maturing in release. It is in this way, bhikkhus, that a bhikkhu, based upon virtue, established upon virtue, develops and cultivates the Noble Eightfold Path, and thereby achieves greatness and expansiveness in wholesome states.”
