This much awaited book describes, using numerous case example, the concept and practice of Dr.Rajan Sankaran s latest and perhaps most significant contribution. The Seven Levels of Experience which enables a homoeopath to know all times, in any given case, where the remedy is revealed. In this completely new way of case taking there is a definitive pathwy from the chief complaint through the different levels to the remedy. A most way to observe and utilize the active energy patterns of the patient (hand gestures and body movements ) is described. This new method, now used successfully all over the world is described extensively in print for the first time.ReviewThis latest book by Dr. Rajan Sankaran is the most evolved and comprehensive of his work to date. As he notes at the beginning, it is the fullest representation of his ideas, both new as well as incorporated from his earlier works. It approaches completeness, with regard to formulating a system of homeopathic case-taking, analysis, prescribing and management (follow-up), knowledge of remedies, and the understanding of how this practise relates to the fundamental principles of nature. In its totality, Sankaran delivers more profound insights regarding all of the above, in a new way, representing a significant advance in the field of homeopathy. In collaboration with his colleagues in Mumbai, he has developed various principles and 'maps' which help to systematise homeopathy. To my knowledge, no one in the field of homeopathy today has attempted anything like the scale of this effort, which is not only based solidly on the firm foundations of homeopathic philosophy, but also opens new frontiers to understanding. The fundamental idea is that a remedy is curative when it is given on the basis of the patient's deepest level of experience, his/her vital sensation. At that level, there is an energy which corresponds to something non-human, something which is like a plant, mineral or animal. It seems like non-sense. It is as if there are two songs playing in the same person: the human part, which is supposed to be there, and the non-human, which isn't. The song of the remedy will express itself with the language of its kingdom: plant sensitivity, mineral structure, or animal survival. It will express itself precisely as the song of a substance. All of Sankaran's previous work culminates here. His observations which led to the classification of kingdoms and miasms were explained in his earlier books, and are recapped in greater depth. In An Insight into Plants (2002) he introduced his model regarding levels of experience, and how this applies to understanding information which the patient gives in case taking. In The Sensation in Homoeopathy, he takes you from the patient, via the levels of experience and the maps of kingdoms and miasms, to the source of the remedy itself. Through his sensitive and skilful case-taking, he shows how to encourage the patient to take you there. The cases selected for illustration have been carefully chosen to provide a suitable range. This amounts to nothing less than a coherent system of practise, one that can be learned and replicated. Central to Sankaran's thesis is the concept of 'levels'. In the chapter called 'Deeper Insights' he expands on this: level one is 'name', two is 'fact', three is 'feeling/emotion', four is 'delusion', five is 'vital sensation', six is 'energy'. Each level arises from the one before, though in a circular, rather than linear fashion: from the level of 'name' (e.g. headache) to 'fact' (worse lying down) to 'emotion/feeling' (it makes me sad) to 'delusion' (it feels as if someone is driving a nail into my head), to 'sensation' (my head is splitting open) to 'energy' (to follow this progression, the source of the remedy might be from the tree family conifers). Equally, you can move in the other direction: 'energy' gives rise to the 'sensation' which gives rise to the 'delusion', which gives r
