Universal significance of the principle of Samanya and Vishesha beyond Ayurveda

There is a fundamental principle in Ayurveda, known as the principle of Samanya (similarity) and Vishesha (difference). While the principle was essentially propounded in the context of yuktivyapashraya (rational medicine) in Ayurveda, here we would like to argue that it has universal applicability in Ayurveda and beyond, across systems and domains of knowledge, including science, technology and humanities, as well as scientific, experiential and traditional knowledge systems. Taking examples of some of the most well-known problems of ecology, economy and society, we demonstrated the universal significance of the principle of Samanya and Vishesha. To illustrate our argument, we have discussed three brief cases, as diverse as family, climate governance, and poverty reduction, and discussed in the light of the Samanya and Vishesha. Evidently, these issues also have larger relevance to public health. Bringing an Ayurveda concept out from its premises is a new order of thinking. The path-breaking insights that were provided, have important implication for deciphering other basic principles of Ayurveda from the perspective of their wider applicability, and thus their robustness. We have indicated a way forward for future research in Ayurveda to develop knowledge-base for evidence-based clinical practice in contemporary society.
