By these lines, the narrator is seen to be able to love his mistress as long as time endures. In describing a very large distance, the author uses this allusion: Thou by the Indian Ganges side / Shouldst rubies find: I by the tide / Of Humber would complain (5-7). This allusion to Ganges, in India, and Humber (England) means that it seemed that the narrator and his mistress are indeed separated by a very great distance.
