bobolink for a chorister
A **chorister** is a church choir member. Dickinson substitutes a bobolink—a songbird known for its bubbling, joyful call—for formal church music.

A **surplice** is the white ceremonial robe worn by clergy and choir. Her "wings" suggests she's already angelic without church costume.

A **sexton** is the church caretaker who rings bells and digs graves. Here it's another bird, turning death's attendant into a singer of life.

Not "getting to heaven at last" (after death) but experiencing it continuously in the present moment. Heaven as ongoing experience, not future reward.
