Astrology helps you on two planes. On material plane, it lets you understand your strengths and weaknesses. It helps you to decide whom to trust and whom not to. It guides you through the right times to conduct right activities. On spiritual plane, it helps you to understand your mission in this life. You can reach the ultimate goal of self-realisation through Astrology. If you do not believe in Astrology, then you cannot get these benefits of Astrology which believers get.
