What metaphors are used in Bliss by Katherine Mansfield?

Early in the novel, images of the sun are used to metaphorically represent bliss. Mansfield later links the image of the sun with the moon through the candle metaphor, which seems to project an ideal order of relationship in nature: "Although it was so still it seemed, like the flame of a candle, to stretch up, to point, to quiver in the bright air, to grow taller and taller as they gazed . . . almost to the rim of the moon."
