Astrology  is a science and it is widely accepted now a days. Destiny is the mirror  of your past karma. You can not change it but you may reduce its bad effect by Mantra, prayer and Gems-stones. Your Horoscope shows what is to be happened in your coming life. Stars  indicate the situation of every incident. Strars reflect your past life. Every Mantra has its own power. You should do it by yourself. Pitrudosh, Kal sarpa yoga,Chandal yoga,Shrapit dosh,Vish yoga all these yoga's bad effect can be reduced by vidhi.

When we get fruits/rewards for our actions in the form of happiness & unhappiness in life, at that time we can see the hand of destiny. We can never fight our destiny.
