The topic sentence needs to relate the paragraph to the thesis statement of the essay. However, you need to make sure that your topic sentence strikes a good balance between the broad and the narrow. Don't write too vague or general an idea or you will never be able to discuss it in a single paragraph.
If you look at each body paragraph as a mini-essay, then the topic sentence is like the thesis statement. It is generally the first sentence of each body paragraph and tells the reader the main point of the paragraph. Just as with the thesis statement, the topic sentence should be neither too general nor too specific.
