so that you will be allowed to live ... Devarim 8:1
This phrase is found in connection to doing the mitzvot of Torah. In order to live, in order to be allowed to return to the Land of the Living from a shamanic Otherworld journey, the mitzvot of Torah must be observed, must be done by those of Jewish ancestry. So, how do we know if we have successfully observed to do the Torah mitzvot of our Jewish Ancestors? We know when we are not only allowed to live, but when we are commanded to return to the Land of Living.
