Is Spirit the breath of life?

I am so tremendously alive and working and enjoying my life here so much. 

It is the grandest, jolliest life you can possibly imagine. All love and kindness from my friends, never an idle wasted minute, never a tired feeling—never anything but the fullest, freest powers of activity here and on your plane. 

Well, it does seem sometimes that my wonderful life here is much more than I deserve.
