Final answer:
Unity in 'The Good Morrow' is represented by the deep spiritual connection between the lovers, resembling the human soul's yearning for union with a higher power as captured by love poets like Rumi, Hafiz, and Kabir.
Step-by-step explanation:
In The Good Morrow by John Donne, unity is shown through the deep spiritual connection between the lovers, which aligns with choice C. The poem celebrates the unity and completeness the lovers find in each other's company, suggesting a world where the lovers create their own microcosm of fulfillment and joy. This sentiment is similar to the unity described in these lines from the thesis statement: "The works of ecstatic love poets Rumi, Hafiz, and Kabir use symbols such as a lover's longing and the Tavern of Ruin to illustrate the human soul's desire to connect with God." Additionally, the atmosphere of another play mentioned where the two lovers could not be together in this world but could be in the afterlife, underscores the theme of spiritual connection and unity beyond the physical realm.
