“If the prayer is not whole many demons pursue it, as is written: All her persecutors overtook her in her distress (Lamentations 1:3). This is why people pray: Yet He is compassionate… (Psalms 78:38). [He atones for] Crime (ibid.)—Samael, who is the Serpent; and does not destroy (ibid.)—the Angel of Destruction; and abundantly takes back His wrath and does not arouse all His fury (ibid.). And we pray that these four [namely: crime, destruction, wrath, and fury] do not pursue the prayer, as many demons are attached to these. There are seven ministers, who have seventy more attached to them. Those seventy bring allegations in each and every firmament through which the prayer passes and seven-hundred myriad demons are attached to them.
If the prayer ascends whole, with the mitsvah of wrapping tallit and tefillin of the head and of the hand, it is said of them: And all the peoples of the earth will see that the name of YHWH is called over you and they will fear you (Deuteronomy 28:10). The name of YHWH—this has already been explained as tefillin of the head. Whoever sees the name יהוה (YHWH) over the head in prayer, which is the name אֲדֹנָי (Adonai), shall immediately flee, as is written: A thousand fall at Your side (Psalms 91:7).
Because Jacob saw through the Holy Spirit the oppression of the last exile, in the end of days, it is said of him, And Jacob was greatly afraid, and he was distressed (Genesis 32:8). As a result, he divided the holy nation in exile into three parts, as is written: And he placed the slavegirls and their children first (ibid. 33:2). This means at first in the exile of Edom: and Leah and her children after them, and Rachel and Joseph last (ibid.). Because he saw their eventual poverty and suffering, he prayed for them: if… I return safely to my father’s house (ibid. 28:21), so that they may have the merit to be redeemed and return to the Temple. He said in prayer: and give me bread to eat and clothing to wear (ibid.).
Because of this exile, David described Shekhinah as hungry and exhausted and thirsty in the wilderness (2 Samuel 17:29), because he saw Shekhinah desolate and withering and then joined in Her sorrow. After he saw that the children of Israel repented with joy, he composed ten types of psalms [cf. Zohar 3:283a (RM); TZ Haqdamah, 3a–b]. At the end of them all, he said: A prayer of the lowly when he grows faint (Psalms 102:10). This prayer encompasses all other prayers and ascends before all other prayers [see Vayiqra Rabbah 3:2; Zohar 3:195a]. The other prayers, sung with a melody, are delayed in being presented before the King, and do not enter, until the prayer of the poor does.
Which is the prayer of the lowly? It is the evening prayer. Since She is without Her husband She is lowly and faint and may be taken freely by anyone. The Righteous One is withered and lowly under the rule of all peoples of the world, every people enslaves them and rules over them. This is similar to the evening prayer, because it is the aspect of the night of exile.
The prayer of Sabbath is a charity given to the lowly as the Masters of Mishnah explained that the sun during Sabbath is charity given to the poor [see BT Ta’anit 8b: ‘Rabbi Yitsḥaq further said: Sunshine on the Sabbath is an act of kindness towards the poor, as is said, But unto you that fear My name shall the Sun of righteousness arise with healing in his wings; and you shall go forth, and grow up like calves of the stall (Malachi 4:2)’]. Therefore, on every weekday a person should make himself a pauper at the gate of the King during the prayer of Amidah for the sake of Shekhinah, that he participate in the sorrow of Shekhinah as did David. He should cover himself with the proper vestments, namely tallit with tassels, as a poor man stands at the gate to the palace of the King, Adonai, because אֲדֹנָי (Adonai) is numerically equivalent to that of הֵיכָל (heikhal), palace. This is why it is said [at the beginning of the Amidah prayer:] Adonai open my lips (Psalms 51:17).
When a person opens his lips during the weekdays at Arvit [the evening prayer], an eagle descends to carry the prayer of the night upon its wings. This eagle is called Nuriel. It is called Uriel from the aspect of Ḥesed and Nuriel from the aspect of Gevurah, which is a burning fire about which is written: A river of fire was flowing and went out before Him (Daniel 7:10) [cf. BT Ḥagigah 13b ad loc.].
During Shaḥarit (Morning Service), the lion descends to receive the prayer with its arms and wings—every living being has four wings—this is the angel Michael. During Minḥah (Afternoon Service), the ox descends to receive the prayer with its horns and wings, and this is the angel Gabriel.
On Sabbath, the blessed Holy One descends with the three Patriarchs [Ḥesed, Gevurah, and Tif’eret] to receive His only Daughter [Shekhinah] through them. This is the secret of the Sabbath which consists of ש (shin) and בַּת (bat), daughter. The three lines of ש (shin) refer to the three Patriarchs. Through them, the blessed Holy One receives the prayer of Sabbath. At that time, the celestial living beings that are called by the name יהוה (YHWH) say, as is written: Lift up your heads, O gates, and lift up, eternal portals, that the King of glory may enter (Psalms 24:9).
At this time, seven הֵיכָלִין (heikhalin), chambers, are opened. The first chamber is the chamber of Love, the second is the chamber of Fear, the third is the chamber of Compassion, the fourth is the chamber of Prophecy from the aspect of the speculum that shines, the fifth is the chamber of Prophecy from the aspect of the dim glass, the sixth is the chamber of Justice and the seventh is in the chamber of Judgment. These chambers correspond to the seven sefirot. The chamber of Love is Ḥesed, Fear is Gevurah, Compassion is Tif’eret, the speculum that shines is Netsaḥ, the dim glass is Hod, Justice is Yesod and Judgment is Malkhut.
Of them is written: בְּרֵאשִׁית (Bereshit), In the beginning, which consists of בָּרָא שִׁית (bara shit), created six; אֱלֹהִים (Elohim) is in the seventh chamber. There are seven chambers below, and seven chambers above. The seven voices that correspond to them appear in the psalm, Grant to YHWH (Psalms 29:1), which includes eighteen [iterations of] יהוה (YHWH). By these the blessed Holy One sails through eighteen worlds according to the mystery of: The chariots of Elohim are myriads, thousands of thousands (Psalms 68:18) and there are 18,000 worlds [see BT Avodah Zarah 3b]. Many guardians of the gates stand before the chambers to receive the prayers and no prayer enters without being measured and weighed.
None can stand before the gate of prayers and prevent any prayer from entering. Of such a one is written: [Like arrows in the warrior’s hand, thus are sons born in youth. Happy the man who fills his quiver with them.] They shall not be shamed when they speak with their enemies at the gate (Psalms 127:5). This is the gate of the King. Since the prayer is a mitsvah and Shekhinah and Torah is the blessed Holy One they must not be separated. Torah and the mitsvah should be elevated with Love and Fear.
There are the 248 words in the recitation of Shema that were given in love and fear, and that are contained in the ה (he) of יהוה (YHWH). Therefore, the blessing: ‘He Who chooses His people Israel with love,’ is recited before the recitation of Shema to indicate that we draw solely from the aspect of Love, which is the mystery of the 248 positive mitsvot. These 248 positive mitsvot are included within Abraham [because אַבְרָהָם (Avraham), Abraham, is numerically equivalent to 248, and his is the quality of Loving-kindness]. It is written of him: The seed of Abraham My friend (Isaiah 41:8).
Tefillin are strength, as they were given from the aspect of Fear, which is the left. This is the Terror of Isaac, because all the prosecutors ascend to demand all the Judgments throughout the worlds. Thus, it is written: And by the arm of His strength (Isaiah 62:8). This is why it is written: Love אֶת יְהוָה (et-Adonai), YHWH, all His faithful (Psalms 31:24). But Tif’eret of יהוה (YHWH) comprises all, as it is the middle pillar. Hence it says of Jacob, And, look, YHWH was poised over him (Genesis 28:13). This was not mentioned in relation to Abraham or Isaac, because Jacob is the aspect of Tif’eret, which includes all, since it is the middle pillar. When called by the name Jacob, He includes the quality of Abraham, וה (vav, he), and the 248 positive mitsvot. Later, when he was called Israel, he rose by יוֹד הֵא וְאוֹ הֵא (Yod He Vav He). The mystery of יוֹד הֵא וְאוֹ הֵא (Yod He Vav He) appears in the expression ‘Israel arose in thought’ (Bereshit Rabbah 1:4) to be created because מַחֲשָׁבָה (maḥshavah), thought, consists of: מַה חַשָׁב (mah ḥashav), ‘What thought.’ מַה (Mah)—יוֹד הֵא וְאוֹ הֵא (Yod He Vav He) [numerically equivalent to מַה (mah)], in which the Holy Name lies. Because of Jacob, who is called Israel, it is written: And Elohim created the human in his image (Genesis 1:27) after the likeness of his Master.
Sons, life and sustenance are drawn down to the lower beings only through the aspect of the middle pillar, of which is written: My son, My firstborn is Israel (Exodus 4:22) [on ‘sons, life, and sustenance,’ see BT Mo’ed Qatan 28a]. This is the Tree of Life, as is written: The tree [grew and became mighty, and its top reached the heavens and its branches to the end of all the earth. Its foliage was lovely and its fruit great, and there was] food for all [in it] (Daniel 4:8–9). As for Shekhinah—Israel below are Her life; Torah—Her sustenance; and prayer—an offering which offers Shekhinah for coupling [with Ze’eir Anpin]. During the exile, it is said that Shekhinah said to Her husband: Give me sons, for if You don’t, I am a dead woman! (Genesis 30:1).
Shekhinah is an offering for the blessed Holy One which He receives with both the right and the left arm, and with the body. His coupling with Her is accomplished by the Righteous One [Yesod, called ‘sign’]. This is the sign of the tefillin, of Sabbath and of the holidays. So when prayer [Shekhinah] ascends [to Ze’eir Anpin] She should be joined with Him with all ten sefirot [because there can be no holiness with fewer than ten] which is His own holiness, His blessing and unity. Therefore, when a person wishes his prayer to ascend, he should raise it with all its movement, the musical intonations and the vowels, since the letters are horses, the vowels horsemen, and the musical intonations weapons. If the serpent aims to seize the prayer, one must prepare a sling against it, and the mystery of the matter lies in זַרְקָא (zarqa), מַקַּף (maqqaf), שׁוֹפָר הוֹלֵךְ (shofar holekh), and סְגוֹלְתָּא (segolta)” (Zohar 1:23a, Tiqqunei ha-Zohar, cf. Zohar 2:86b).
