"Let there be light"
Rabbi Yosi explains here that the Light spoken of is concealed and illuminates only the righteous; it has no purpose in the world. Rabbi Yehuda says that the world is sustained by that Light which is concealed yet sown like a seed. A thread of this Light emerges wherever people are studying Torah. "Yet the Creator will command His steadfast love in the daytime, and in the night His song shall be with me." When Moses erected the tabernacle, a thread of this Light emerged to form a cloud over the Tent of Meeting, and it is what renews the Creation daily, even now. Rabbi Yosi then comments on, "So he set it before them, and they ate, and left some of it over, according to the word of the Creator," which, we learn, means that whoever hears these teachings always finds new meaning and inspiration in them.
The primordial Light spoken of in the phrase, "Let there be light," illuminates us, bringing spiritual renewal and transformation to the world. For the first time in human history, myriad threads of Light are drawn and woven into a blanket that envelopes, warms, and unites all mankind, as our eyes embrace these ancient texts that shine with such splendid spiritual power.
