Astrology has always been a fascinating subject to the mankind and the Cosmos ever remained a great mystery in spite of having been widely explored by the scientists. Taking birth in a traditional Vaishnavite family of India, I am also motivated towards this subject right since my childhood. Coming in contact with Mr. Yogendar Nath Dixit, a teacher of Mathematics at Allahabad (India) with profound knowledge of Indian astrology, in 1963, I learnt many more interesting characteristics of the subject from him during my long association with him. It was October 1995 when I was compelled to give a talk in an “International Conference on Integrated Systems of Medicine” organized at the Banaras Hindu University, Varanasi (India) by its organizers, I selected this topic and prepared a lecture (in English) with due consultations with many scholars of the subject. Varanasi has been well-known since ages for its scholars in astrology too. With my long expertise of mathematical training, I have tried to present here various aspects of astrology (with special reference to Indian astrology) in brief. Many explanations are given here in of mathematical tabular form that makes comprehension of the complex subject easier.
