What's the difference between enlightenment and nirvana?

[Key Elements]

Let's get deeper into this topic, if we can and if you dare.  I think Leo already said that they are one and the same, right @Leo Gura ? Correct me if I'm wrong. In some ways, I do agree with Leo, simply because we are one, but I disagree if a person says that the definition is the same. Why would they even have different names if the definition is exactly the same?

Thoughts?

We already had too many of these debates. They lead nowhere because people all have their own opinions and personal definitions.

You must do the practices to discover what such spiritual words mean.
