To reach to a conclusion about any aspect of life to what will happen in future, an astrologer, takes into account number of factors in the horoscope, i.e. star signs, constellations, sub constellations Rashi,, the position of 12 houses their lords, conjunctions, aspects at the time of birth as well as at the time of the prediction. Destiny is supreme. No one can change destiny & as an astrologer, I too believe in the same manner.
