The Looking-Glass of Life

 .

If your heart were sincere and upright,

every creature would be unto you a looking-glass of life

and a book of holy doctrine.

Thomas à Kempis

Thomas à Kempis (c. 1380 – 25 July 1471) was a late Medieval Catholic monk
and the probable author of The Imitation of Christ, which is one of the best known Christian books on devotion.
