True the world becomes more SPACIOUS when we focus on the moment and thus see that to save one life is to save the world. This is why it is important to translate spaciousness as spaciousness and not emptiness.
Are "spacious" and "empty" words that are confused or mis-translated?
Is "spacious" a word that has a use in Buddhism?
A search for "spacious" on Access to Insight suggests that word is used, but is not used often and not used canonically.
I think "empty" usually means "empty of self", am I right? I.e. when people say "empty" do they mean Anatta?
