Astrology is an integral part of Indian culture. It is as old as the vedas. It explains the celestial phenomena and the corresponding terrestrial events. It explains the cause and effect of events. The main basis of astrological thought is that the celestial phenomena effects the life and events on the earth. It does not permit anyone to conclude any event just as an accident. Celestial bodies generate a lot of energy m their movements and astrology shows us how we can use these energies operative m our lives in the best possible way. Astrology is a science which helps the mankind to put their life in the right path. Astrology was tested and experienced for many centuries and it’s knowledge was handed down the ages to new generations. A study of the civilizations flourished m different parts of the world shows that Astrology played an important role m their life. The places where astrology does not flourish are mostly barbarious, lacking in knowledge and they don’t have any communication with the universe. In India, astrology has been considered as the best guide to achieve the fourfold objectives of life and they are Dharma, Artha, Kama and Moksa All the activities of human being are directed towards the achievement of these goals and astrology helps us to achieve them in a organized manner. Astrology has reached this stage after nullifying the criticisms, which it has to face from the beginning itself. Astrology has the seven visible grahas - Sun, Moon, Mars, Mercury, Jupiter, Venus and Saturn along with the two lunar nodes - Rahu and Ketu . Rahu and Ketu are accepted as grahas in Indian astrology only. They are considered as shadowy - grahas. The details available about Rahu and Ketu are confusing. Astrological texts don’t have a unanimus opmion about Rahu - Ketu. These opinions create confusion in the mind of astrologers as well as astrology followers. So, there is a need of study on Rahu - Ketu. Rahu - Ketu are considered as recent developments by many scholars But, this is not true. Their references are available m vedas itself. So, with a view to give some clear opinion on Rahu - Ketu, I have chosen this subject for study. Further, we know that astrology is the most criticized subject and research in this field are very less. So, I have tried to answer these criticisms and I hope that my study will encourage more researches in this field.
