It's not vegetarianism or Yoga, but beef and Islam that India has been exporting to the world.
India has been the world's top-most exporter of Islam for more than 100 years. I don't think even Saudi Arabia comes anywhere close to India in terms of this export prowess. India was the virtual Hejaz (housing Mecca and Medina), the centre of Islam, of the 20th century.
(India was also the fifth largest exporter of beef in the world in 2017.)
Here's how Islam -- made in India, Deoband in Saharanpur district of Uttar Pradesh to be precise, and exported to the region that makes up Pakistan and Afghanistan -- created the Taliban which established the most virulently medieval Islamist regime in recent memory (in Afghanistan).
The Made-in-India Islam created the Dar-ul-Uloom Haqqania in Akora Khattak in Khyber Pakhtunkhwa, which is the alma mater of Taliban. It's founder Maulana Abdul Haq actually studied in Deoband in Saharanpur.
The Made-in-India Islam has been complicit in war, terrorism and ethnocide of epic proportion in Pakistan and Afghanistan.
