Rajan Sankaran — biography and Sensation method

Rajan Sankaran is the Mumbai physician-homeopath who turned a single clinical intuition — that beneath a patient's symptoms lies a non-human "sensation" the remedy must match — into the most influential of the contemporary prescribing systems, taught from Bombay to the seminar circuits of Europe and the Americas. His method evolved across two decades of books, from The Spirit of Homoeopathy to The Sensation in Homoeopathy and the Schema, and sits alongside Jan Scholten's element theory and Massimo Mangialavori's families as the third pillar of the post-1990 generation.

Career in brief

Sankaran was born in 1960 into a homeopathic family — his father, P. Sankaran, was a respected Bombay practitioner and editor — and trained in homeopathy before building the Mumbai practice and teaching organization that became the engine of his method. He has taught internationally since the late 1980s, and the school he leads (the "Bombay school" or "the other song" group, after one of his book titles) runs case-based courses and an annual programme that have carried his approach to thousands of practitioners. Sankaran belongs to the figures who, after George Vithoulkas reopened the question of the mental and emotional totality, rebuilt case analysis around new organizing principles in the 1990s and 2000s.

The method: levels, kingdoms, and the sensation

Sankaran's system is best read as a sequence of refinements rather than a single fixed doctrine. The early work reframed the case around the patient's central disturbance — a "delusion" or false perception driving the whole picture — and argued that disease is a posture the organism adopts against a perceived threat. The middle work introduced the three kingdoms: plant patients lead with sensitivity and reactivity, mineral patients with structure and the fear of losing it, and animal patients with survival, competition, and the question of victim or aggressor. The classification is a triage tool — decide the kingdom, then narrow within it — and it is the part of the system most visible in everyday seminar practice.

The mature work added the two ideas the method is now named for. The first is the levels of experience: a case can be heard at the level of name, fact, emotion, delusion, sensation, or energy, and Sankaran teaches the interview as a descent through these levels toward the "vital sensation" — a bodily-felt experience shared by the patient and the source substance. The second is the Schema: a tabular mapping of plant families, mineral rows and columns, and animal subkingdoms to their characteristic sensations, used to locate a remedy once the kingdom and level are clear. The workflow is therefore: take the case to the deepest accessible level, read the sensation, place it in a kingdom and family via the Schema, and confirm against the materia medica.

The published works

The arc is cumulative: each book absorbs and reframes the last, which is itself a fair criticism — a reader must know which stage a given term belongs to. Sankaran's own framing in The Other Song is that the sensation method supplements rather than replaces classical totality prescribing.

Traditional indications and internal critique

The sensation method has generated a substantial casebook literature, with practitioners using it across chronic constitutional cases, pediatric presentations, and cases where classical keynote prescribing has not resolved. The kingdom classification in particular has become a standard teaching scaffold for differentiating between broad remedy families before narrowing to genus and species.

Three methodological critiques recur within the field. The first concerns reproducibility: the sensation is an interpretive endpoint, and whether two practitioners reach the same sensation from the same interview is a live question; the method's answer — discipline the descent through levels and confirm against materia medica — relocates rather than removes the subjectivity. The second concerns the relationship to provings: kingdom-and-family attributions are partly deduced from natural taxonomy, so a remedy's attributed sensation can outrun the prover symptoms that classically anchored it, a concern Scholten's element system attracts in the same form. The third concerns interview technique: the level-by-level descent can shape the patient's language toward the working hypothesis, which Sankaran addresses in his teaching on non-directive case-taking but which remains a live methodological question.

The Sensation method inside 2026 software

Sankaran's apparatus has a real digital footprint. The Schema, the plant and mineral classifications, and the level model ship as structured reference data inside several repertory platforms, and dedicated tools built around his school's material let a practitioner move from kingdom to family to remedy on screen rather than in the printed Schema. In practice this runs two layers at once: a sensation-method practitioner works the school's classification material alongside a general repertory for classical totality analysis and case management, then audits where the two shortlists converge. The classical side of that workflow — descended-from-Kent repertories, case management, totality analysis — is what a tool like Similia Pro covers.

Verdict

Sankaran is the contemporary generation's systematizer of depth: the author who built the interview into a descent through levels, mapped kingdoms and families to sensations, and shipped the result as both a library of books and a queryable Schema. Read The Spirit of Homoeopathy and The Other Song for the method's logic and its self-correction, and treat each kingdom-and-sensation placement as a hypothesis to be confirmed case by case against the materia medica.
