As a kid, I watched the original Star Trek on TV over and over about a gajillion times.
"Space, the final frontier...."
Space is abundant in my life. I don't mean a big house. I mean time not filled, empty time = space. It is a difficult challenge to not fill it. It is also difficult to let your entire spiritual life and practice consist of nothing but space. Space is truly the final frontier. It is beyond the ordinary busy life. It is beyond TV. It is beyond religion. It is nothing at all.
Space means cutting back on the number of thoughts. Letting the world become thin by thinking less of it. Letting your small self become thin by denying its thoughts.
