Dear sirs, I have a horoscope with Saturn and rahu in the ascendant Taurus and Saturn is in retrograde. 3<SUP>rd</SUP> house has Jupiter and moon (cancer) and jupiter is in retrograde. 7<SUP>th</SUP> house(scorpio) has mars ,venus and ketu. 8<SUP>th</SUP> house(saggitarius) has mercury. Mercury is again in retrograde. 9<SUP>th</SUP> house has sun(Capricorn). The exact DOB is 18<SUP>th</SUP> janaury 2003, 3.18pm, bangalore. I have just started learning astrology. I have the following doubts. Is Saturn yogakaraka? I read that Saturn presence in lagna is not very beneficial for Taurus lagna. Is presence of mercury in 8<SUP>th</SUP> house good or bad? Jupiter in 3<SUP>rd</SUP> house with moon is good or bad? Rahu and ketu being exalted in 1<SUP>st</SUP> and 7<SUP>th</SUP> positions(further they are vargottamma occupying same positions in rasi and navamsha) would they be beneific or malefic? How to interpret the results of Saturn Jupiter and mecury which are in retrograde? Would venus be a functional malefic? Thanks in advance.
