"Shiv Sharma is an inspiring yoga teacher who is also a scientist. His upbringing in India gave him a sound understanding of the development of Indian philosophy whilst his subsequent scientific training instilled an essential desire to explain the world and seek justification for whatever is asserted. As a yoga teacher, he applies these principles by separating what is non-testable, or downright wrong, from what is measurable, understandable and repeatable; his mantra in class is to question, understand and apply well-directed effort." - Dave Plummer, ex-Head of Medical Imaging, University College London Hospital and Lesley Whitby
