Many astrologers predict your life chart based on Dashas and Transit (Gochara). Gochara Phala is the study of planetary movement as per the placement of the Moon in your Natal (Birth) chart. While predicting Gochara results, the moon plays a significant role and the sign in which your natal moon is placed is termed as your Janam Rasi (Birth sign). Since the planets constantly move from one rasi to another rasi, Gochara results are drawn by interpreting from the natal moon to planets in transit.
