The Words Fall in

A disciple asks the rebbe, “Why does Torah tell us to 'place these holy words upon your hearts'?  Why does it not tell us to place these hold words in our hearts?”

The rebbe answers, “It is because as we are, our hearts are closed, and we cannot place the holy words in our hearts.  So we place them on top of our hearts. And there they stay until, one day, the heart breaks and the words fall in.”
