Question:

What does Emily Dickinson's reference to "amber hands" mean in "The moon is distant from the sea"?

I have been going over this poem, and I am beginning to understand it, but that one phrase is killing me! Does anyone know what it means or what she's referring to here?

The Moon is distant from the Sea
by Emily Dickinson

The Moon is distant from the Sea—
And yet, with Amber Hands—
She leads Him—docile as a Boy—
Along appointed Sands—
He never misses a Degree—
Obedient to Her Eye
He comes just so far—toward the Town—
Just so far—goes away—
Oh, Signor, Thine, the Amber Hand—
And mine—the distant Sea—
Obedient to the least command
Thine eye impose on me—

Amber hands are hands that are on fire...glowing from the angel that leads the person.
