36. Rabbi, which mitzvah is gedolah (great) in the Torah?

37. And Rebbe, Melech HaMoshiach gave this teshuva (answer) to the Baal Torah, VAHAVTAH ES ADONOI ELOHECHA BCHOL LEVAVCHA UVCHOL NAFSHECHA UVCHOL MODECHA (And thou shalt love the L-rd thy G-d with all thy heart and with all thy soul and with all thy might [DEVARIM 6:5]).

38. This is the gedolah and rishonah mitzvah.
