The popularity of yoga is hilariously touted as a precursor of things to come. The prime minister has created an "international" yoga day. They assume this will be followed by international adoption of ayurveda, cow "science", cow worship, renaming of several mathematical and scientific discoveries after Indian gurus who supposedly discovered everything originally in the veda.
The don't seem to be aware that modern yoga practised in the west is a modern invention by an Indian fitness instructor who was attempting to capture a portion of the American fitness market jumpstarted by eugen sandow. Most of the so called asanas have been incorporated into yoga from modern gymnastics.
