Applying that to the spiritual side of life - well, our spirituality should be intuitively obvious to the casual observer. Why do we hide it? So it can't be observed by anyone else? Or is it that we, as observers, don't know what to look for or how to respond to it when we see it.
What a shame! Simply put, spirituality shows forth as support for our fellow human beings. We should easily recognize expressions of love. Such observations are intuitive. Is it that we are afraid that if we observe or even become involved ourselves, that we will suffer some great trauma? It is written, love is gentle, love is kind. Where's the fear in that?
Funny thing is that engaging either as an observer or as a participant will result in a good feeling which lasts far longer than the pleasant taste of a chocolate peppermint patty.
