The study of repertory is a fascinating journey into the nuances of decision making for homeopathic practice. If we have to find an analogy for cybernetics, perhaps repertory would stand out as an outstanding example of foresight that the homeopathic stalwarts had, much before the computing technology gained ground. The objective processing of data into information that makes sense and knowledge that enables application of such information is the hallmark of repertorisation. Such a significant tool of prescription should be studied as a skill enhancing instrument and not just as an epistemological offshoot of homeopathic ideology. It is seen that very often the study of repertories is relegated to cramming the structure of some important repertories and remembering some important rubrics till the formality of course assessment is completed. More often, the study of repertory is seen with a disdain that a redundant exercise attracts. This book is an effort to infuse vibrant dynamics into the attitude of learner vis-à-vis the understanding and application of repertory. Any skill learning gets the respect that is due, depending on the value of such skill. Prescription is a skill that every homeopath would cherish to acquire. This attainment comes with experience and evidence. The background knowledge that facilitates this skill realisation is seeped into the methods of case taking, case analysis and case processing. Repertorisation is only a culmination of these exercises. The thrust of this book is to provide spotlights on the issues that enable the process of repertorisation. This book is an efforts to provide contemporary approach to homeopathic methodology with a firm foothold in the classical perceptions of homeopathic concepts. There are sprinklings of nuggets drawn from fields such as psychology, logic, philosophy, linguistics, etc. These are studded to trigger critical thinking and openings to link homeopathic wisdom with other related streams of prudence. This book is intended as reference book for undergraduate and postgraduate students of homeopathy, as well as to the serious learners of homeopathy. It is hoped that the profession will provide unbiased feedback to improve the future editions of this book.
