science, accusing them of defaming traditional and alternative medical practices.
Most people confuse science with logic. Anyone can be logical, even analytical, in establishing causality. But science is about stepping outside the human mind, relying on measurement, comparison and evidence.

Such a relationship is widespread in the art world — in music and dance circles.
It is also seen in spiritual circles. Nothing moves without the guru's permission or approval. Of course, the student insists the submission is voluntary.
This guru parampara, contrary to popular belief, did not always exist in India.
