This week's portion is called Yitro, named after Moses' father-in-law. The most significant event in this parashah is the Giving of the Torah, when the Children of Israel (that is, the descendants of Jacob) became the Jewish People. At that time, this group of people, standing at the foot of Mount Sinai, was given the mission they were to perform for all generations until the coming of the Messiah.
We find in the Torah that God created the universe with Ten Phrases (Mishnah, Pirkei Avot 5:1). Then we find that God gave Ten Commandments. Hasidic masters explain that we should project the Ten Commandments onto the Ten Phrases with which the world was created: the light of Torah (Ten Commandments) should illuminate worldly affairs (Ten Phrases). What does this mean in practice?
Some consider the world to be an undivided thing, and the Torah to be an undivided thing. The result of this perspective is that, when a person is in a Torah-based environment, they behave as a "Torah Jew," while when they are in a secular environment, that is, in the world, they behave according to the ideas of society and the world in general.
Taking the idea a step further, the worldly perspective doesn't even involve carrying out Torah prohibitions, God forbid, but rather the religious person approaches the Torah with a worldly perspective: he doesn't watch football games on Shabbat, but makes sure to find out the result minute by minute from "others".
The Giving of the Torah was the moment in universal history when God chose, thus empowering, the Jewish people to imbue the world with holiness through the Torah's instructions (in terms of laws and good conduct). It is not required that a person separate themselves from the world or withdraw from society; that is, it is not right to disregard the incredible technological advancements of the last hundred years. Rather, the proper approach is to use those resources for holy purposes and in a holy manner.
