Dhp 337-338 · Thirst
This salutary word I tell you, `Do ye, as many as are here assembled, dig up the root of thirst, as he who wants the sweet-scented Usira root must dig up the Birana grass, that Mara (the tempter) may not crush you again and again, as the stream crushes the reeds.' As a tree, even though it has been cut down, is firm so long as its root is safe, and grows again, thus, unless the feeders of thirst are destroyed, the pain (of life) will return again and again.
