Let’s take a look at wealth. The Rebbe writes “There is nothing wrong with wealth per se, as long as we take the necessary steps to ensure that we retain the proper perspective. We should answer the challenge of wealth by striving all the more to refine our human-animal natures, taking care not to indulge in excess mundane gratification – material or cultural. We can then refine the world, as well, by shining the light of the Torah outward,1 using the blessings of wealth for their intended purposes: to support and further the study of the Torah and the dissemination of Judaism.2
If we encounter someone who has “gotten fat and kicked,” we should not give up hope, since even the most disinterested Jew remains a Jew at heart, and the light of truth will penetrate even the hardest barrier.3 Sefer HaMa’amarim 5700, p. 158. 2. Sefer HaSichot 5702, p. 149. 3.Sefer HaSichot 5701, p. 83.
G‑d then told Moses to inform the Jewish people how G‑d would provide them with material bounty in the Land of Israel. But G‑d also cautioned them that should they overindulge in this wealth, it would cause them to rebel against Him.
[Moses said,] “The [formerly] upright people became fat and kicked.” Deuteronomy 32:15
