While addressing an event in Shillong on September 25, Rashtriya Swayamsevak Sangh (RSS) Chief Mohan Bhagwat said that our ancestors travelled to a lot of countries but never conquered them, furthermore he said that they taught Mathematics, Science and Ayurveda in foreign lands.“Our ancestors have done great things... We taught Mathematics, Science & Ayurveda... Even today we do the same, who helped Sri Lanka during crisis & provided them loans? India did. Who gave vaccines to the world in Covid? We did,” said Bhagwat in Shillong.
