But alas, the world thinks that to nourish the physical frame is enough to preserve life.

Although not enough, it must still be done; this cannot be neglected.

For if one is to neglect the physical frame, better far to retire at once from the world, since by renouncing the world one gets rid of the cares of the world.

There is, however, the vitality which informs the physical frame; that must be equally an object of incessant care.

Then he whose physical frame is perfect and whose vitality remains in its original purity--he is one with God.
