אִם־אַחֶ֖רֶת יִֽקַּֽח־ל֑וֹ שְׁאֵרָ֛הּ כְּסוּתָ֥הּ וְעֹנָתָ֖הּ לֹ֥א יִגְרָֽע׃
만일 상전이 달리 장가를 들지라도 그의 의복과 음식과 동침하는 것은 끊지 못할 것이요

One great strategy for achieving this is by clinging to the Torah, for through this one clings to the Shechinah even during one’s life. Then all the more so will one merit clinging to it after death. Thus it is related in the Zohar (Parashas Va’eschanan 268a): Rabbi Acha and Rabbi Elazar were standing together one evening after midnight engaged in study. Rabbi Elazar began a discourse: “It is written, ‘For it is your life and the length of your days that you may dwell upon the earth’ (Devarim 30:20). Come and see. The Shechinah only settles in a place where Torah is studied and in the merit of study is the world sustained. This is the meaning of the words, ‘For it is your life…that you may dwell upon the earth.’ “But if people fail to study it is said, ‘For what was the land lost? And Hashem said, ‘Because they abandoned My Torah” (Yirmeyahu 9:11-12).” Then he added: “This applies to one who is able to study and does not.” Rabbi Elazar likens this to the case of a modest and pleasant woman whose husband sets aside his conjugal duties (see Shemos 21:10) and abandons her, causing her to cry out to Heaven concerning her abandonment.
