Bardo is a word that comes from the Buddhist religion. It's a special word that describes a time when someone has finished one thing and before they start something new.
For example, think of when you finish playing with one type of toy and you're not sure what toy to play with next. That's a mini bardo!
In Buddhism, people believe that when someone dies, they go through a much bigger bardo. This is a time when their soul is in between living and being reborn. It's like being in a waiting room before going on to the next part of life.
During this big bardo, people believe that the person who died is still aware of what's happening around them but they can't talk or move. They also believe that the things that the person thinks about and sees during this time affects where they'll be reborn next.
So, a bardo is all about being in between one thing and the next, and in Buddhism, it's a special time for people who have passed away to transition into a new life.
