Why Chochmah is considered to have 32 paths
By saying that 32 paths expand from Chochmah, it means that the Torah, that is Zeir Anpin, is included in the 22 letters and the ten sayings. Rabbi Shimon also says that this Chochmah is a father to the fathers, and that in it there are a beginning and an ending.
73. This Chochmah OF 32 PATHS is the first beginning. From it 32 paths expand. THIS MEANS THAT the Torah, WHICH IS ZEIR ANPIN, is included in the 22 letters and the ten sayings. This Chochmah is a father to the fathers, CHESED, GVURAH AND TIFERET OF ZEIR ANPIN. In this Chochmah there are a beginning and an ending, WHICH ARE therefore CALLED upper Chochmah and lower Chochmah - THE FORMER IS THE BEGINNING AND THE LATTER THE ENDING. When Chochmah expanded TO ZEIR ANPIN it is called a father to fathers. Everything is included only in this CHOCHMAH, as it is written, "in wisdom have You made them all" (Tehilim 104:24).
73. הַאי חָכְמָה שֵׁירוּתָא דְּכֺלָּא, מִנֵּיהּ מִתְפַּשְּׁטָן תְּלָתִין וּתְרֵין שְׁבִילִין. וְאוֹרַיְיתָא בְּהוּ אִתְכְּלִילַת בְּעֶשְׂרִין וּתְרֵין אַתְוָון, וַעֲשַׂר אֲמִירָן. הַאי חָכְמָה אָב, לַאֲבָהָן. וּבְהַאי חָכְמָה, שֵׁירוּתָא וְסִיּוּמָא אִשְׁתְּכַח. ובג"ד, חָכְמָה עִלָּאָה חָכְמָה תַּתָּאָה. כַּד אִתְפְּשָׁט חָכְמָה, אִקְרֵי אָב לַאֲבָהָן. כֺּלָּא לָא אִתְכְּלִיל אֶלָּא בְּהַאי. דִּכְתִּיב כֻּלָּם בְּחָכְמָה עָשִׂיתָ.
