“The pure air
is cleansed of lingering lees
And mysteriously,
Heaven's realms are high.”

Context: There is a spiritual obligation, there is a task to be done. It is not, however, something as simple as following a set of somebody else's rules. The noetic enterprise is a primary obligation toward being. Our salvation is linked to it. Not everyone has to read alchemical texts or study superconducting biomolecules to make the transition. Most people make it naively by thinking clearly about the present at hand, but we intellectuals are trapped in a world of too much information. Innocence is gone for us. We cannot expect to cross the rainbow bridge through a good act of contrition; that will not be sufficient.
We have to understand. Whitehead said, "Understanding is the apperception of pattern as such"; to fear death is to misunderstand life. Cognitive activity is the defining act of humanness. Language, thought, analysis, art, dance, poetry, mythmaking: these are the things that point the way toward the realm of the eschaton. We humans may be released into a realm of pure self-engineering. The imagination is everything. This was Blake's perception. This is where we came from. This is where we are going. And it is only to be approached through cognitive activity.

Context: Everything on this planet has something to do with music. Music functions in the realm of sculptured air. Polluted as our atmosphere might be, air is the thing that makes music work. Since all other things that occur in the sound domain are transmitted to the ear through that swirling mass, depending on how wide you want to make your definition, you could perceive quite a bit of human experience in terms of music.
