As it is said in the Mahaparinirvana sutra, there is no higher perception than that of impermanence. By contemplating death,—and near death,—the being drives the lowly dimension out of himself, isolates himself from worldly desires, and precludes the manifestation of pride. Becoming aware of the impermanence of everything on this earth, the ignorance characteristic of the lower human model becomes impossible. Death does not surprise the one who prepares for it and considers each day as the possible last. The perception of impermanence makes the futile unmistakable and prevents the being from moving away from the essential.
