Fully ordained female Buddhists are called nuns and typically dress in all white unlike the monks who are draped in saffron robes. I prefer the saffron worn by the monks. Like the monks, the nuns shave their heads.
This woman was part of a group of nuns and monks kneeling and prostrating next to the Bodhi tree while echoing the prayers uttered by the monk leading the worship. I would like to have understood their ritual utterances but they were in a language I did not recognize. (Sadly, I am only fluent in one language which is a curse inherited by many of us born and raised in the US.) I did not even recognize the script on the cover of this woman’s book.
