Normally, when we say “Jyotish”, we always thinks that, it gives the information about human affairs and all the major and minor events of life by studying the movements and relative positions of “planets” in the universe which affects us the life of human beings since their  birth on this earth.

But the term “Jyotish” is not restricted to that only. It also emphasises that how should a human being “behave” and “work” according to his “destination or aim” of life which has been “decided by the god” for him.

This generates a question in the mind:

What is the “ultimate objective” of getting birth on this earth?

For “what purpose” we are here and how we are making efforts to attain that “ultimate objective.”?

 Let us first discuss the "Planets" in the universe,  the “Zodiac Sign and its Ruler Planets” in which any person get birth:
