Writing The Torah On The Walls Of The Heart

Question: What does it mean to write the Torah on the walls of your heart?

Answer: The walls of the heart are the most evil, stony desires. That is why it is allegorically written that the Torah has to be written not on the internal, softer part of the heart, but on the external part.

To write means that all changes that we have to undergo and that are described in the Torah have to be reflected on our general egoistic desire called “our heart.” In that way, we gradually correct ourselves and the hearts that were at least partly involved in this movement.
