The sutras define all-pervasive suffering as such: whether it exists or dissipates, one does not experience any suffering; nonetheless, it is called all-pervasive because it leads to other kinds of suffering.

All-pervasive suffering exists mainly in the form and formless realms. Sentient beings there do not experience notable suffering such as birth, aging, illness, and death, nor happiness such as good health and longevity. These beings are reborn in the form and formless realms because they attained meditative absorption in their previous life — a state of meditation which is inherently subtle and tranquil and which does not, as a result, produce any feeling of significance at the moment of rebirth. Although the form and formless realms do not have suffering or happiness, they are nevertheless impermanent; hence sentient beings there only experience all- pervasive suffering, not suffering of suffering or suffering of change.
