what do you all see in spiritualism?

[Mr Greene]

So "spiritual" = 'emotional'... Feels like we're back with the theists...

I wouldn't want to live an unemotional life, myself. I regard the good life as being, for me, balancing emotion and reason.

Never said you should but I don't think spiritual should be a synonym for emotional.
I think following that path leads the wrong way. 

Personally I see 'spiritual' as being about the nature or characteristics of factors in our environment, be that a desert, forest, beach, suburbia or the financial markets.
For this reason I'm always a little more edgy with claims of "being one with the universe" because it isn't our environment, we don't live out there.
Unless you're Buzz Aldrin the chances of space being your environment are a little short.

All his life has he looked away... to the future, to the horizon. Never his mind on where he was. Hmm? What he was doing.
