Out through the in door

Those on deathbeds, why so grave?
You whimper to deaths door.
Don't you recall our brazen steps
Crossed through it once before?

Voices wailing, fists sailing,
We hated going through,
Leaving behind what makes us whole,
A fault we've long since rued.

So there’s no cause to dread the day
We’re back in Nirvana;
We’re lying there outside this dream--
And simply must wake up.
