The word die has various usages: to desire extremely, to fail a game, to cast or mold, to disappear or seclude, and to have orgasm. Dickinson used them all in various poems. Key words in following three poems: 1) scarce, 2) mystic creature, 3) certificate.

I died for Beauty-but was scarce 1
Adjusted in the Tomb
When One who died for Truth, was lain
In an adjoining room-

He questioned softly "Why I failed"? 5
"For Beauty", I replied-
"And I-for Truth-Themself are One-
We Brethren, are", He said-

And so, as Kinsmen, met a Night-9
We talked between the Rooms-
Until the Moss had reached our lips-
And covered up-our names-
(F.448/J.449)
