First thing’s first, Buddhism and Hinduism are VERY different religions. However the are grouped together here because three of the five flags that feature Buddhist symbols jointly feature Hinduism.

Since there are only five, I’ll comment on each one.

Nepal

Oh Nepal, you vexilogical wonder! It is the only non-quadrilateral national flag on Earth. Its two points represent the Himlayas or the two dominant religions, Hinduism and Buddhism. No one can decide. They also say that if you mirror it over the flag pole, you get the shape of a stupa! Kudos for being unique and doing your own thing. Though you make it difficult to fit you in a flag grid…

India

By law, the flag must be made of khadi, a type of silk made famous by Ghandi himself. In the one month I spent in India, I couldn’t find ONE Indian flag to buy for my collection. In my research for this article, I learned that it was only in 2002 where the flag was permitted for use by private citizens! The extremely specific flag code could be the reason I couldn’t find one. That, and most Indians have very little disposable income and probably wouldn’t waste it on a piece of cloth they couldn’t use anyway.

Cambodia

It’s like your national flag is a big marketing pitch. “Come to Cambodia and see our one tourist attraction!” No offense to Cambodia. (Actually, yes offense to Prime Minister Hun Sen. You are a very bad man. Shame on you.) The Angkor Wat is a very important historic site for all of humanity, no matter what religion you are. Go see it.

Bhutan

This is probably up there with the top most bad-ass flags on Earth. Sporting their national symbol, Druk the Thunder Dragon, and the colors of Tibetan Buddhism, this is a flag no collection should be without! Bhutan is also the world’s happiest nation! And it’s obvious why…their national symbol is a Thunder Dragon named Druk!

But the winner of the most Buddhist flag goes to…

Sri Lanka

The gold throughout represents Buddhism as well as the four Bo leaves representing the four main concepts of Buddhism: Mettā, Karuna, Mudita and Upekkha. Also, you can’t lose when you have an angry(?) lion-y-thing wielding a dagger.

Unless maybe you are DRUK THE THUNDER DRAGON!
