On one hand, it’s impossible to be dead. Death is non-existence, non-being. “To be” is existence, being. “Be dead”, therefore, means “exist in non-existence”, or “be non-being”. How can it be possible? It’s absurd. It’s a self-contradictory statement. There’s no such thing.

On the other hand, that’s exactly what enlightenment is. So, if you can figure it out, you’ll gain an instant enlightenment. Hehehe.
