The purpose of looking at one’s horoscope is to get an idea about how life will be in this birth based on your deeds in previous life. Astrology is capable of giving you a blue print of this. This can be achieved by evaluating a horoscope details of which are given in detail in my blog navagrahastro.blogspot.in which will give you a mathematical idea about the how astrology can be used in this regard. The mathematics behind astrology is so complex and in the olden days the astrologers used to make general predictions by looking at yogas which are tantamount to treating a patient just by looking at him and using the clinical sense of a doctor which most of the time worked because medicines are only tools to cure a disease while in fact the diseases are cured by the body on its own. While God created your body and soul, he has also incorporated the techniques your body needs to cure oneself in the event of having a disease. There is a joke that “The body cures itself and Doctors take the Fees”.
Today a doctor diagnoses the patient using Lab Reports, Scanning and other modern means and what they get is an evaluation in empirical terms of the various results of such screening using which the doctor comes to a decision how to cure him or aid him in curing his diseases by surgery or replenishing the health by certain medicines.
You will understand all this once you read my articles on the blog.
