Written as a plea to a loved one, "Light" begins in sadness. The speaker asks to have their tears kissed away and their sorrow traced by someone close. From there the mood shifts toward hope. Light, the speaker says, stays light whatever its colour, which reads as a quiet belief that goodness and comfort survive every kind of pain or difference.
The speaker wants to be changed by this love: to stop worrying about the future and simply live it, and to treat perfection as something to aim for rather than something shameful. The closing image is the most striking. The loved one is a wolf and the speaker is the moon, a pairing that suggests the two belong together under the same night sky. No dawn will break the "spell" around them, so the night becomes a safe place rather than a threatening one. The poem ends calm and certain, with two people feeling "one" and fully alive.
