When we see towards the sky one question is arises in our mind what are the "Grah" and "Nakshatra"? Why some of the planets do not show in the day and night? and why all planets do not show together? these are the questions for what people started to understand the Planets and Mercuries. And people understood the movement and round of these planets slowly-slowly. And he started to connect all the incidents with the Planet and Asterism, and because of that, it had been an implement, named by Astrology (Jyotisha).
In Vedas (Vedic Literature) we can get a standard definition of Astrology. Many religions have connected importance to astronomical matters, such as Indians, Maya, Chinese. Western astrology is one of the oldest astrological methods which is still in use, one can discover its roots to the 19th-17th century. Western astrology is linked with the system of horoscopes that purport to describe aspects of a person's personality and predict notable events in their lives. These events are based on the positions of celestial objects.
While the 20th century, astrology has been challenged strongly on both theoretical and experimental grounds, and it has been proved to have no scientific validity or explanatory control. Thus astrology lost its academic and theoretical standing, and a general belief in it has largely declined.
While polling studies have demonstrated that almost 25% of Americans, Canadians, Britons say that they continue to believe that star and planet positions affect their lives, astrology is now recognized as pseudoscience. People say that the astrology rose in India because the ground of Indian Jyotish Shastra is almost 8000 years of old.
