Varahamihira was a really smart man who lived a very long time ago in India. He was like a superhero scientist, who knew a lot about astronomy, math, and medicine.
He studied the sky and was able to predict things like when an eclipse was going to happen, and he made really cool inventions like a sun dial that helped people tell time during the day. He also knew how to use math to plan things like building canals so people could have water for their farms.
Varahamihira didn't just study astronomy and math, he was also very interested in medicine. He believed that if our bodies are balanced, we will be healthy. He even wrote about what foods and herbs we should eat to stay healthy.
Overall, Varahamihira was a very important and very smart man who helped us learn a lot about the world around us.
