More than the Grave is closed to me — Equivocation

Grave is repeated three times here. The dullness (grave) of the solemn (grave) life is like death (grave) to Dickinson. She amused herself with poems of nothing to others, and everything to self.

More than the Grave is closed to me－
The Grave and that Eternity
To which the Grave adheres－
I cling to nowhere till I fall－
The Crash of nothing, yet of all－
How similar appears－

(F.1532/J.1503)
