**Astrology** has been rejected by the scientific community as having no explanatory power for describing the universe.
But in Hindu religion, Astrology consists of a number of belief systems that hold that there is a relationship between astronomical phenomena and events or descriptions of personality in the human world.
If you see, it's actually a belief system without any backing from Science.
Believing on it is completely on you, especially how you perceive it and use it in your daily life.
If you completely depend on it, I would personally not recommend doing so!
Astrology and Kundli could be extremely advance science which scientist are not aware of until today, which is possible too, as Human beings have not explored science completely, or, It possible could also be no effect in your life!
Go with Trial and Test and see how it ends up on you! But don't completely depend on it!
Do you have any very specific question, feel free to ask counter question!
