A temple stay is like spending the night at a special place called a temple where people go to practice their religion. Temples are usually very quiet and peaceful and they have special rooms called halls where people go to worship or pray to their god or gods.
During a temple stay, you get to live like the people who stay there and practice their religion. You might wear special clothes, eat special food that the priests or monks make, and sleep in a special room called a dormitory.
You might also get to do fun things like learn how to make crafty things like prayer beads or try out some meditation. The people who live at the temple might give you lessons on how to live mindfully and make good choices for your life.
It can be a really neat way to learn about another culture and way of life, and maybe even learn some new things about yourself!
