Segment 1א׳

גּוּלְגַּלְתָּא דְּרֵישָׁא חִוָּורָא, לָאו בֵּיהּ שִׁירוּתָא וְסִיּוּמָא. קוּלְטְרָא דְּקִטְפוֹי, אִתְפְּשָּׁט וְאִתְנְהִיר, וּמִנֵּיהּ יַרְתוּן צַדִּיקַיָּיא ד' מְאָה עָלְמִין דְּכִסּוּפִין לְעָלְמָא דְּאָתֵי. מֵהַאי קוּלְטְרָא דְּקִטְפָא, דְּהִיא גּוּלְגַּלְתָּא חִוָּורָא, נָטִיף טַלָּא כָּל יוֹמָא, לְהַהוּא זְעֵיר אַנְפִּין, לַאֲתָר דְּאִתְקְרֵי שָׁמַיִם, וּבֵיהּ זְמִינִין מֵיתַיָּיא לַאֲחַיָּיא לְזִמְנָא דְּאָתֵי. דִּכְתִּיב, (בראשית כ״ז:כ״ח) וְיִתֶּן לְךָ הָאֱלֹהִים מִטַּל הַשָּׁמַיִם. וְאִתְמַלְּיָיא רֵישֵׁיהּ, וּמֵהַהוּא זְעֵיר אַפִּין, נָטִיף לַחֲקַל תַּפּוּחִין. וְכָל חֲקַל תַּפּוּחִין, נְהִירִין מֵהַהוּא טַלָּא.

The skull of the White Head: in it there is no beginning and end. The vessel of its balsam spreads out and shines, and from it the righteous shall inherit four hundred worlds of longing in the world to come. From this vessel of balsam, which is the white skull, dew drips every day to that Small of Countenance, to the place that is called heaven; and by it the dead are destined to be revived in the time to come, as it is written, “So God give you of the dew of heaven” (Gen. 27, 28). And His head is filled, and from that Small of Countenance it drips to the field of apples; and the whole field of apples shines from that dew.

Segment 2ב׳

הַאי עַתִּיקָא קַדִּישָׁא טָמִיר וְגָנִיז. וְחָכְמְתָא עִלָּאָה סְתִימָאָה, בְּהַהוּא גּוּלְגַּלְתָּא מִשְׁתְּכַח, וַדַּאי בְּהַאי עַתִּיקָא, לָא אִתְגַּלְיָיא אֶלָּא רֵישָׁא בִּלְחוֹדוֹי, בְּגִין דְּאִיהוּ רֵישָׁא לְכָל רֵישָׁא. חָכְמְתָא עִלָּאָה, דְּאִיהִי רֵישָׁא, בֵּיהּ סָתִים, וְאִקְרֵי מוֹחָא עִלָּאָה. מוֹחָא סְתִימָא. מוֹחָא דְּשָׁכִיךְ וְשָׁקִיט. וְלֵית דְּיֵדַע לֵיהּ, בַּר אִיהוּ.

This Holy Ancient One is hidden and stored away. And the supernal hidden chochmah (wisdom) is found in that skull. Certainly, in this Ancient One nothing is revealed but the head alone, because it is the head of every head. The supernal chochmah, which is the head, is hidden in it, and is called the supernal brain, the concealed brain, the brain that is still and quiet; and there is none who knows it but He.
