Greetings from Astrologer Kishore Kumar Jain.
When reading a birth chart, it's best to start with the big picture and then move to the details. You usually follow a plan, going from a general look at the chart's structure to describing specific personality traits.
The first step, the overall analysis, helps you understand the main personality features and highlights some points that you'll later confirm or adjust with a more detailed look. These general traits are always kept in mind.
