Kabbalah su Esodo 23:26

Rabbi Elazar opened with the verse, "Open you my eyes, that I may behold wondrous things out of Your Torah" (Tehilim 119:17). How foolish men are, for they do not know, and do not seek to be occupied with, Torah. Torah is the whole life. All freedom and all goodness in this world and in the World to Come are contained within it. It is life in this world; namely, they may merit full days in this world, as it is written, "The number of your days I will fulfill" (Shemot 23:26). And one will merit long days in the World to Come, for this whole life is a life of joy, life without sadness, life that is real life, freedom in this world, freedom from everything, because other nations cannot rule over anyone who is engaged in the study of Torah.
