The various astrologies of India have, over the course of many centuries, been combined and transmuted into a rare, fascinating and intricate discipline known as "jyotish" (light). Still an intrinsic part of India's religious and cultural life, it is also a universally applicable model which can easily adapt to western conditions. This book seeks to present jyotish not simplistically, but in a way that makes the subject accessible to the modern western reader, and at the same time to place it in the context of the many other disciplines - including philosophy, medicine, economics, astronomy and religious ritual - which it embraces.
