Prognosticating disease is a very important aspect in Predictive Astrology. After all, disease, decay and death are common factors that affect life.
Prognosticating disease astrologically assumes significance due to two main reasons:
First, it would forewarn the native of the nature of the disease that would afflict him enabling him to take timely action either to ward it off or take such measures as necessary to mitigate its effect.
Secondly, it would help the physician to diagnose the disease.
We have explained in a previous article that Astrology is not Fatalism in that it does not say that something predicted by a study of planetary influences is inevitable. The main purpose of Astrology is to predict a possible a misfortune or a fortune in advance to ready the native to meet the situation. If it is some misfortune, a disease or some other misfortune such as loss of wealth or a fatal accident, the native could take timely action to avert the eventuality or mitigate its adverse effect.
As regards helping the physician to diagnose the disease, though there is no argument about the medical science like any other science being highly advanced today, still there are cases where certain diseases defy diagnosis even through the use of the highly sophisticated advanced equipment. In such cases, a competent astrologer can help a physician by providing a clue to correctly diagnosing the disease.
Most students of Astrology may know that it is the 6th House in a horoscope that provides the clue to the nature of possible disease that could afflict a native. The 6th House if afflicted could, of course, also create enemies and cause the native fall into debt.
As explained by Indian Jyotish Guru Dr. B.V. Raman in his celebrated work, Predictive Astrology, diseases are denoted by the 6th House, planets aspecting it, its lord and the Navamsa occupied by the 6th lord.
The significators or karakas for the 6th House are Saturn and Mars and their strengths or weaknesses also should be taken into account when assessing the 6th House with regard to ascertaining the possibility of disease, the nature of the disease and the part or the parts of the body to be adversely affected.
The Zodiacal sign falling in the 6th House signifies the affected the part or parts of the body. And its lord signifies the nature of diseases likely to be caused by it. It is noteworthy that each afflicted planet associated with the 6th House can cause more than one disease during its Maha Dasa or Antar Dasa.
