The Torah comes in two forms: written and engraved.

On the last day of his life, Moses inscribed the Torah on parchment scrolls. But this written Torah was preceded by an engraved Torah: forty years earlier, at Mount Sinai, the Divine law was given to us in the form of Ten Commandments etched by the hand of G‑d in two tablets of stone.

When something is written, the substance of the letters that express it—the ink—remains a separate entity from the substance upon which they have been set—the parchment. On the other hand, letters engraved in stone are forged in it: the words are stone and the stone is words.

By the same token, there is an aspect of Torah that is "inked" on our soul: we understand it, our emotions are roused by it; it becomes our "lifestyle" or even our "personality"; but it remains something additional to ourselves. Yet there is a dimension of Torah that is engraved in our being. There is a dimension of Torah which expresses a bond with G‑d that is of the very essence of the Jewish soul.
