The original meaning of "Buddha"
Buddha is considered to be a god-like being in Buddhism, but it does not originally have such a religious meaning.
The word "Buddha" is derived from a term meaning "awakened one", and it refers to a person who has achieved enlightenment.
Achieving enlightenment in Buddhism does not originally mean going to the afterlife or becoming a god-like being in a religious sense.
When you continue to meditate in the correct way, you will come to a moment when your mental state changes significantly.
As a result, you can see the world from a higher dimension than before, gaining mental freedom and stability.
The original meaning of the word "achieving enlightenment" is to reach the above-mentioned mental state through meditation.
In short, a Buddha originally means a human being who has achieved the above-mentioned mental state through meditation.
It is a living human being, not a god or anything close to it.
