All the work is only where there are two ways, as we have found, “and he shall live in them, and he shall not die in them.” And the meaning of “shall be killed but shall not breach” applies only to three Mitzvot. And yet, we also find that the first Hassadim gave their lives on actions.
But in truth, this is the whole work. When one should keep the Torah, this is the time of the heavy load. And when the Torah keeps the person, it is not at all difficult, by way of “one’s soul shall teach one.” And this is considered that the Torah keeps a person.
