Look deep into the Torah, which contains everything. In the question: As you look again and again, you will discover new things.

("Ben Beg Beg says, "Turn it over and turn it over, devour it, and make a plan for it...for you have no good measure of it" - Avot 5:19-22, and also: "And you ate it, old and old...this is the Torah. This desire that was hidden in the house of its treasures from before the six days of Genesis...Israel is commanded to turn it over and turn it over" - Y. Borla/ Kissufim, 247)
