When we start realising that our parents were correct what they said and one what they did it is that time when our children starts thinking that we do not know anything. this is what we call it as Karma is a boomerang. whatever we do it comes back to us. This is why we say please do not hurt others by thought, word and action.
The idea that "karma is a boomerang" means that the actions and behaviors we exhibit will ultimately come back to us, either in positive or negative ways. This concept implies that our choices and actions have consequences and that we will eventually experience the results of our behavior. In this context, the phrase "karma is a boomerang" is a reminder to treat others with kindness and respect, as our actions can have a lasting impact on those around us and ultimately come back to us in the future.
