Quotation
“Because I feel that in the heavens above The angels, whispering one to another, Can find among their burning tears of love, None so devotional as that of 'Mother,' Therefore, by that dear name I have long called you, You who are more than mother unto me.”
Edgar Allan Poe
The idea behind the quotation
The speaker believes even angels know no love more devoted than a mother’s, and calls someone “Mother” because she has been more than one to him.
