Astrology is the study of the connection between macrocosm and the microcosm. Everything in this universe is connected. But astrology is not fatalistic. It is about probabilities. It just gives you a roadmap. It gives you an idea or an overview of how things are.
But, there are many free choices of yours, like there are many exits on the highway. If you take a picture from the sky, you can see the entire highway, but there are many exits and the car can take any exit. That choice is there.
So, life is a combination of freewill and destiny. It is not only freewill or only destiny and astrology is a way to know about it.
But the more important thing is the impact of your practices. Meditation and spirituality are one step higher than astrology. Your meditation, compassion, work, and attitude can change things.
