Please let me know or let someone else at the Yeshiva answer my question re the following. The subject is the Shabbat Hymn composed by the Ari, which appears on p. 180 of the new Chabad Siddur, Tehillat HaShem, particularly, verse 4: "May the Shechinah be surrounded by six loaves on each side [of the table]; and may they correspond to the two sets of six loaves and other articles [of the Beit HaMikdash]." I know the standard meanings and significances of the loaves, but wish to know more, about the relationship of the Shechinah to the lechem panim, and their mystical function, as explained by the Ari, especially as in the context of this verse. I want to ask you to let me know where can I access the commentaries on this verse 4, such as: Eit HaZamir, by R. Yaakov Berkovitch, Siddur Otzar HaTefilot; and Siddur of Rabbi Yaakov Emden, and R. Yaakov Koppel on Siddur Ari Zal, Kol Yaakov. Also from, V. Zohar II, 88a, and b'naniyn tit'katar, b'shiyt nah'amei lis'tar. Thank you very much, Shemaia

Dear Rabbi/s, Do you have any info on the mystical prayer for the month of Nissan, where for thirteen days we are to recite the prayers re the offerings brought by the Nassi of each tribe, see p. 391 of Tehillat HaShem, the new Chabad Siddur, e.g. ".... gather and take in those sacred "birds" to the holy place ...." I need the explanation of "birds," the sacred place, as well as the second paragraph of the prayer. Gratefully yours, Shemaia
