There are many intricate rules concerning the construction of a succah that are presented in the Gemara and codified by the poskim. Rav Yosef Karo, author of the Shulchan Aruch, states in Orech Chaim 631:3: “The standard manner of placing the schach upon the succah is to do so in such a way as to enable one to see the large stars through it.” In his celebrated work, Mishnah Berurah, the Chafetz Chaim explains that the large stars in this statement refer to those that can be seen during the day prior to sunset. In addition, he notes that many latter-day authorities rule that even the nighttime stars need to be visible through the schach. Regardless as to which stars are being referenced in these classic Rabbinic sources, we must ask a straightforward question, namely, why did our Sages mandate that the stars should ideally be visible through the schach of the succah?
Rabbi Mordechai Yoffe discusses this question in his work, Levush Malchut (Orech Chaim 631:3): “And it is highly preferable that its covering [the schach] should not be very thick, rather, [it should be comprised of materials that] allow the large stars to be seen from within [the succah]. After all, this is the meaning of the term, ‘succah’ that is stated in the Torah, and standard schach is normally comprised of such [materials].”
The contemporary scholar, Rabbi Raphael Sindler Sadin, in his work, Pnei HaShulchan, suggests that Rav Yoffe is indirectly ruling that “one ought not to make a thick covering [of schach], for in that case, [the succah] would then become like a house [and the stars would no longer be visible from under the roof]. In sum, in order to maintain the temporary nature of the succah, its schach should be thin and allow for the large stars to be seen from within.
While Rav Yoffe focuses on the requirement to maintain the temporary aspects of the succah’s construction, Rabbi Yosef ben Meir Teomim (1727-1792), in his work, Pri Megadim, provides us with a spiritual analysis as to why we ought to be able to see the stars through the schach: “So that one will remember Who created all of this [the stars] and enables us to dwell upon the earth. As it is written: ‘When I see Your heavens, the work of Your fingers, the moon and stars that You set in place’.” (Tehillim 8:4) By extension, Rav Teomim intimates that Chazal wanted the Festival of Succot to be a powerful teaching moment wherein we could become acutely aware of Hashem’s Creation and our place in His universe. As Dovid HaMelech declares in an oft-cited verse: “How great are Your works Hashem, You made all of them in your supernal wisdom, the entire cosmos is filled with Your creations.” (Tehillim 104:24)
I would like to offer another possible answer to the question, “Why did our Sages mandate that the stars should ideally be visible through the schach of the succah?”
Chazal were acutely aware of the need to instill G-d-consciousness in each of us. Without a sense of Hashem’s direct presence and immanence in our lives, it is impossible to feel He is our Yedid Nefesh (the Beloved of our Soul) and protector. The siddur gives powerful voice to this notion during the Friday night tefilah, “And spread over us the succah of Your peace. Blessed are You Hashem, Who spreads the succah of peace upon us and upon all His people Israel and upon Jerusalem.” Quite beautifully, and in ways words alone cannot truly express, we ask the Almighty to actively reach out to us in this expression of hashgacha pratit (Divine providence) and surround us with His succah of peace. This, I believe, is one of the feelings that our Sages wanted us to experience when we gaze at the stars from under the frail schach of our succot.
May it be G-d’s will, and our heartfelt desire, that Succot will be a time we truly feel His Divine presence encircling and protecting us as we gaze at His stars above our succot. V’chane yihi ratzon.
