Ti-lakkhana

Ti-lakkhana is a concept in Buddhism that describes the three characteristics of existence, which are impermanence, suffering, and non-self.

Let's pretend you are playing with your favorite toy. Even though you love playing with it, one day it might break, get lost or you might lose interest in it. That is what is called impermanence, which means that everything in the world is constantly changing and cannot stay the same forever.

Sometimes when you are playing with your toy, it might accidentally hurt you or you might feel sad if you have to share it with someone else. That is what is called suffering, which means that sometimes things can make us feel bad or cause us pain.

Finally, even though your toy might make you feel happy, it doesn't define who you are or make you who you are. That is what is called non-self because nothing in the world can fully define who we are or what we are.

So, ti-lakkhana is just a concept that helps us understand that everything is always changing, sometimes things can make us feel bad, and nothing defines who we are completely.
