Ašvieniai is a Lithuanian folk belief that talks about a pair of mythical horses that are believed to bring good luck and happiness.
Imagine two magical horses, that fly through the sky and bring all kinds of good things with them - like happiness, good luck, and sometimes even wealth.
People in Lithuania believe that by doing certain things or following certain traditions like singing songs, dancing, and performing rituals, they can attract these two horses into their lives.
So, ašvieniai are kind of like superheroes who bring happiness and good things to people who believe in them and make an effort to invite them into their lives.
