While we would have heard of astrology and birth charts, every birth chart can be divided into sub-charts that can help analyze the depths of certain aspects of life!
Professional astrologers (especially the ones who have been practicing across generations) take one look at the horoscope or birth chart of an individual, and will be able to predict the reason the individual has sought an astrologer and the current issue/challenge they are facing in life! It was interesting to understand how someone can predict before even one can ask a question. There is a separate stream of astrology that focuses on the time a question is asked (instead of the birth chart) to predict and suggest remedies for a given question.
Now, the sub charts are also called as divisional charts.

Reading a chart seems to be an art in itself. If you know basic chart reading, the divisional charts seem to be extremely helpful in zoning into the exact issue!
