In other words, the righteous have no right to demand tranquillity in this world. We must attempt to reconcile ourselves with Chazal s statement. Yaakov literally went through a life of misery. Yitzchak also achieved prominence and material success. There is ostensibly no prohibition against enjoying the fruits of this world.
Commerce is commendable as long as it is performed in accordance with Torah dictate.
We are permitted any material benefits that we reap through methods that are above reproach. We are expected to utilize opportunities to enjoy a lifestyle of Torah and avodas Hashem, helping those institutions and individuals who are in need. Indeed, shortly before his death, the Gaon M Vilna lamented that he was leaving a world where, for just a few coins, one can purchase a pair of tzitzis, for which he would merit Olam Habah. It is not as if we fear that a tzaddik might receive too much of This World. We may foster divergent attitudes, however, towards material possessions in This World.
