I could not agree with you more and I suppose what we hold dear to our hearts is our 'light at the end of the tunnel',
(back to the light?) well maybe that's the 'spiritual light' we envisage.
So what is our strength?
Living within the laws of nature or listening to our spiritual inner self?
Perhaps they compliment each other.
If that's true and one of those is missing we then become out of kilter with life itself and perish.
