The word, Buddha, is not the name of a person.
It simply means a person who has been enlightened.
Then, what is being enlightened?
In my opinion, it is simply being aware of who you are.
So this little boy is also a Buddha. I don't think he has made so much money and donated it to a religious organization.
But this little Buddha's smile makes me feel very happy. He can make people happy by being himself, not by doing something impressive.
Doing something impressive doesn't always make people happy, including yourself by the way.
There is nothing difficult here. All you need to do is relax.
