Oh, Mrs. Moore.   I find this character in Forster's novel, "A Passage To India," very interesting.  Maybe it is because Forster is alluding to philosopher G.E. Moore though this woman, but themes, central ideas, and symbols follow her wherever she goes.  The two that stick out to me the most are religion and the wasp. 

Mrs. Moore is "the Christian one" in the story.  She speaks often of God, love, unity, and loving one's neighbor.  This is important to note because she sincerely believes in these things and exemplifies them throughout the story.  She, unlike most, enjoys the company of the Indians and is interested in their culture, despite her being English.  However, her Christianity continues to tie her closely with the British which he realizes is not always a good thing.  She slowly begins to question her religion as the story goes on.  The character (I assume symbolically) named "Godbole" mirrors her doubt in his songs.  Questioning her religious beliefs also keeps her tied to the reader as this is a highly relatable struggle that occurs in all societies. 

Mrs. Moore also has a very personal moment with a wasp.  In general, wasps are not pleasant creatures.  Most people either avoid them or try to kill them.  Mrs Moore, however, comforts and speaks with the bug.  Let's think of the wasp as the Indians.  In the mind of the British, Indians are the lowest of the low.  They have nothing to offer except annoyances and inconveniences.  Like the wasp, people either avoid them or try to do away with them.  Mrs. Moore is kind to the wasp just as she is kind to the Indians.  This is significant to note as the wasp will most likely continue to represent the Indian people.
