In Vedic Astrology the Navamsa or 9th Harmonic chart (D9 chart) is said to be a microscopic view of the 9th House and therefore the hidden undercurrent of our fate. It is basically to predict marriage life of the native, spouse and life in later stage (after 32 years). The rasi chart (D1 chart) is your physical existence, the circumstances you live in, the things you do. The D9 chart is the hidden force, invisible hand of destiny that decides the results of your deeds.
