That the Torah is everywhere and in everything. In particular  the letters of the Torah are in everything. Not that everything is Divine. But that there is Divinity in things. Even in Evil there is divinity. For without God making everything exist nothing could exist. But the Divinity in Evil is hidden. But if it would be open Torah inside of Evil the the Dark Side would have nourishment from open Torah. So instead in evil is hidden Torah.
The Torah as a whole is in principle contained in the Ten Commandments. These were hidden in the world until they were revealed at Mount Sinai. These commandments are thus contained in a hidden way in the ten statements of creation. The hidden Torah inside of evil is in the first hidden statement of creation, the מאמר הסתום. So one can find God even if he has fallen  from holiness. One can return to God even from the lowest depths of Hell.
