What does the ending words of "Catch the Rainbow" (by Rainbow) chorus mean?
If "life is not a wheel of chains made of steel", what is?
And why the singer asks to be blessed?
Exact lyrics are
But life's not a wheel
With chains made of steel
If you go for a long bicycle ("wheel") trip, especially at night, and if your bicycle's chain is not made of steel but of a brittler material, I assume you'll fear at every moment that something may go wrong and you'll ask to be saved from any misfortune ("blessed"). This is just my understanding, though.
