You cannot take itself — Greediness

You cannot take itself 1
From any Human soul-
That indestructible estate
Enable him to dwell-
Impregnable as Light 5
That every man behold
But take away as difficult
As undiscovered Gold-
(F.1359/J.1351)
[1, 2] itself, Human soul:: the greediness.
[3] estate:: nature, constitution.
[4] dwell:: to linger, to stay in the wild digging gold.
[5–8] Greediness is impregnable as man's view on gold mine, that everyone has the chance to get rich.
[8] undiscovered Gold:: alluding the gold rush.
