This book details the study of the ancient art called 'Jyotisha' (popularly known as vedic astrology) from a modern-day scientific perspective. It describes the varying states of consciousness in beings and the relationship between human consciousness and light. The book reinstates astrology as the study of the impressions of celestial lights on beings and in particular, human life. Under this context, it describes the important astrological techniques used for predictions in the dimensions of human life including the time periods of varying emotional journeys such as joy, peace, stress and sorrow. Finally, using these techniques, the examples of few renowned personalities are studied to serve as an unshakeable proof of evidence that the study of Jyotisha is scientific.
