Here is another example of a simple error of omission that could have been caught if the student had read the essay aloud or given it to a friend to read. The word "of" should be between "calculation" and "the." That one small error makes the entire sentence awkward and confusing. If the instructor has to reread the sentence to try to understand its meaning, the flow of the essay is interrupted. If this happens often enough in the essay, it gives an overall bad impression on what otherwise might be a very good paper in terms of research.
Ammu is in love with the untouchable man Velutha. She has known him all her life and although he is untouchable, Ammu's family has treated him with a certain amount of respect. However, this does not mean that they would accept a relationship between her and Velutha. Therefore, on some days , Ammu cannot help feeling happy, although sad about the fact that he is untouchable for her. She sometimes wakes up to the sound of music, just as anyone being in love does. Still, Ammu knows that the laws say Let it Be. However, as the reader delves further into the plot, Ammu is touched by the untouchable Velutha. Thus, the line "I wake up to the sound of music, Mother Mary comes to me" refers to their nightly meetings. Mother Mary is Baby Kochamma, speaking for the rules given by Christianity and Caste systems and yet, Mother Mary is also love, in the shape of Velutha. Through this maze of imageries the reader can understand how Baby Kochamma hates Ammu.
Since you mentioned Elijah and Moses I believe it’s pertinent to mention something.
At the Transfiguration Christ spoke with both Moses and Elijah and both Moses and Elijah had, in the end, completely failed in their assigned missions due to disobedience. Moses was not allowed to enter the promised land and a whole generation of Israel died in the wilderness. God appointed Elijah to annoint kings and he didn’t annoint them and was taken up by the Lord. Yet as both law-giver and prophet Christ accomplished for us what both Moses and Elijah could not and did not.
