Every Main Birth Chart (also known as a D-1 Chart) may be further 'dissected' and divided into more minute detailed "mini-charts" (sections). Each 'mini-chart' is not an astronomical chart as is the Main Chart. The Main Chart is practically a photo of the sky at the time of your birth, whereas the Divisional Charts are an "extraction" of the Main Chart. Therefore, these Divisional Charts are not 'read' the same as the Main Chart (the D-1 Chart). There are specific rules that you must know in order to be able to 'read' the Divisional Charts properly. This concept is akin to health where what you see on the outside, our face and body, may not be the health we have in the inside, our muscles, skeleton, and organs. The same with the Main Chart versus the "inside" Divisional Charts. You have to look inside to see further what is happening on the outside.
