This book is an attempt at making the complicated and confusing language of the Organon simpler for students and beginners for easy understanding. Also, the format is simple and tends to build interest in the reader for the subject which is otherwise difficult to comprehend. The most important chunk of topics from the Organon has been dealt with in the present publication (ie: the theory of miasms, chronic diseases, their causation and nature, and susceptibility) The three basic miasms have been explained very much in detail with respect to their origin, manifestations, indications and remedies.
