Precisely, I thought the "Feel free to enjoy nothingness for a minute:" quite apt. :x

I read that as "there is nothing that can be taken away from you"

Same frame of mind I think, slightly different way of expressing it. :P

Accepting that everything has an end and nothing can't be taken away from you is fine, but this doesn't mean you should not focus more on things that can't be taken away from you easily (i.e. until you die).
