In some editions of the Siddur, several words are added to the text of Baruch She'amar on Shabbat. However, these additions are incorrect. The text of Baruch She'amar – which, according to tradition, was revealed to the Ansheh Kenesset Ha'gedola (Men of the Great Assembly) on a piece of paper that fell from the heavens – contains precisely 87 words, and this is the exact text that we should recite. There are some editions of the Siddur in which additions for Shabbat appear before Baruch She'amar. One may recite these additions, though he should ensure to have in mind that they are not said as part of Baruch She'amar, but rather comprise a separate text. The custom is to stand during the recitation of Baruch She'amar. However, since standing is required only by force of custom, and not as a strict Halachic obligation, one who is ill or otherwise frail may sit. Our custom is to hold the front two Sisit of the Tallit in our hand during the recitation of Baruch She'amar. This is based on a Kabbalistic teaching mentioned in the Sha'ar Ha'kavanot (a work based on the teachings of Rav Haim Vital, 1542-1620), according to which there is a deep connection between Baruch She'amar and Sisit. The Ben Ish Hai (Rav Yosef Haim of Baghdad, 1833-1909) adds that one should kiss the Sisit upon concluding Baruch She'amar, as an expression of love and affection for the Misva of Sisit. In the phrase "Ha'mehulal Be'feh Amo," there are some who say "Be'fi" instead of "Be'feh." However, this is incorrect. The proper text is "Be'feh." Significantly, the word "Be'feh" in Gematria equals 87 – the number of words in Baruch She'amar. The correct pronunciation of the final word of Baruch She'amar is "Ba'tishbahot," and not "Ba'tushbahot." One who arrives in the synagogue late, and skips Pesukeh De'zimra in order to recite the Amida together with the congregation, does not recite Baruch She'amar afterward. This Beracha is to be recited only before the Amida. (This applies also to Yishtabah, the concluding Beracha of Pesukeh De'zimra.) The first four words of Baruch She'amar are "Baruch She'amar Ve'haya Ha'olam," the first letters of which (Bet, Shin, Vav, Heh) spell the word "Be'shaveh" – "equal." This has been understood as alluding that reciting Baruch She'amar properly earns us rewards equal to the rewards granted to the angels for serving G-d. Moreover, these four words express praise to Hashem for bringing the world into existence – and so reciting this blessing properly helps us tap into G-d's creative powers. So often, we need Hashem to bring us a salvation, to "create" a solution for us. People frequently approach me asking how they can earn something that they so desperately need. One thing we can do is to recite Baruch She'amar properly, slowly, from the Siddur, and with concentration, thinking about how Hashem created the world from sheer nothingness, and in this merit we will, please G-d, be worthy of Him "creating" the solutions that we all need in our lives.
