There are in all 16 charts according to Indian astrology, however only 3 are mostly studied – the ascendant or lagna chart,
moon chart and sun chart. The most accurate predictions are made using lagna
chart. The lagna chart is divided in 12 ‘rashis’ or houses and the 9 planets
are positioned in these houses as they were during a person’s birth. Whether
the effect of planets would be favorable or unfavorable depends on the way they
are positioned in the houses in the lagna chart.
