Shearer’s early thesis centres on the difference between mind and body yoga. Written primarily for a Western audience, the book carefully explains how yoga, understood there as a range of breathing exercises and meditative practices, is in fact a mere subset of a larger universe whose ultimate goal is self-actualisation.
As an example, he cites the looser meaning today associated with “hatha-yoga”, which has come to mean intense postures and tough breathing exercises, including the practice of nauli, the cleaning of the abdomen by a circular movement of the abdominal muscles, popularised by Baba Ramdev.
The original hatha-yoga was far more rigorous, requiring practitioners to undertake, sometimes for years, “sitting, squatting, remaining standing on one leg, holding the arms in the air, sitting by blazing fires in the full heat of the summer sun or immersed in freezing water in the winter cold”.
