Gasa is a type of poetry that comes from Bhutan, which is a country in South Asia. It's special because it's meant to be sung or chanted, not just read silently like a storybook.
It's like singing a really cool song, except instead of just talking about a boy or being happy or sad, Gasa usually talks about big ideas like love, happiness, and Buddhism. It helps people think about these ideas and feel more connected to each other and the world around them.
Gasa also has something called "rhyme" which means the words at the end of each line sound the same. Rhyming makes the poem easier to remember, like when you sing a song with a catchy tune, you can remember the lyrics much better.
Overall, Gasa is like a really cool, special way of using words and music to think about and feel big ideas about life and the world.
