What does the chariots at the gate in Emily Dickinson's the soul select her own society means?

In Emily Dickinson's poem, "The Soul selects her own Society," the phrase "Chariots at the Gate" symbolizes external pressures and expectations that attempt to influence the soul's choices. It suggests that the soul is discerning and selective in choosing its companions or influences, resisting outside forces that may attempt to intrude upon its autonomy.
