Sīla: Virtue
Salt preserves meat from rot; sīla, the Buddhist training in ethical conduct, preserves a life and a community from moral decay. The verse declares that the disciples already carry this quality, the way salt already has its nature before it touches food. Sīla in early Theravāda teaching is not a checklist but a living, active quality that permeates whatever it contacts. The question the verse raises is whether that quality will be allowed to work.
Viriya: Diligent Effort
Salt sitting sealed in a jar does nothing. Viriya is the energy that takes a good quality from an inner state into actual effect in the world, the animating force that keeps sīla from becoming mere reputation. In the Theravāda path, viriya is one of the five spiritual faculties, named precisely because a faculty without exercise goes slack. The salt metaphor presses the same point: the quality must be put to use, or it is as if it never existed.
Pamāda: Heedlessness
The Buddha's final words were a warning against pamāda: "strive without heedlessness." Pamāda is not a dramatic fall but a slow drift, the gradual relaxation of attention that lets the fire go out while the person assumes it is still burning. The verse's warning mirrors this exactly. Salt does not lose its savor in a single moment of crisis; it loses it when no one tends the quality. The danger is not an enemy from outside but the slow loosening of care from inside.
Moha: Delusion
The Greek word for "losing savor" here (moraino) is rooted in the same word used for "becoming foolish" or "senseless," as in Job 6:6 where flat food has lost all taste. Moha, the root delusion, is that same fogging of discernment: a person still moves through the forms of a spiritual life but no longer tastes what it is for. The salt still looks like salt. It has the shape, the title, the history. But moha has replaced inner clarity with confusion about what actually matters, and the result is form without function.
Kamma: Intentional Action and Its Fruit
"Cast out and trodden underfoot" is not punishment delivered from above; it is the ripened fruit of action emptied of intention. In Buddhist teaching, kamma is the principle that intentional action, driven by genuine care and clear seeing, produces effects that matter, while action hollowed of that quality leaves residue that others discard. The trampling in the verse is the natural fruit of a life that goes through the motions while carrying nothing of substance. The seed determines what grows; the quality of the action determines what it produces.
