The speaker of this short poem is wrestling with loneliness and with a part of themselves they can't quite tame. In the first stanza they say they would "borrow a lost god," an odd, wistful wish. The god isn't there to comfort them. It is there "to hinder" them, to get in the way with a "hard and slippery light." That light sounds hard to hold and uncomfortable to look at, as if even help would come with a cold edge.
The second stanza turns more human and more honest. The speaker invites guests and wants to be merry, but admits the reason: "I could not be alone." The cheer is partly a cover for fear.
In the last stanza, the speaker describes whatever they truly are as "naked," something that "would have stayed out / all night." The poem suggests a raw, wild self that resists the party and prefers the dark. The title, "Best of enemies," fits that split. The mood is quiet, uneasy and tender, with a little dry humor.
