Adam Deeds Klipot (Shells – Negativity) Lights Purification Serpent Shells (Klipot)

72. Similarly, there are bunches of lights of Klipot that come into the world from the supernal primordial serpent that seduced Adam. They are appointed to learn the secret deeds of the world. Therefore, when a man wishes to be purified, he receives help from above, and the help of his Master encircles and protects him. He is then called 'holy.'

72. כְּגַוְונָא דָא, כַּמָּה חֲבִילֵי טְהִירִין, נָפְקֵי לְעַלְמָא, מֵהַאי חִוְיָא עִלָּאָה קַדְמָאָה, דְּאִתְפַּתָּא בֵּיהּ אָדָם, וְכָלְהוֹ מְמַנָּן בִּסְתִירוּ עוֹבָדֵי עַלְמָא, וּבְגִין כָּךְ, אָתֵי בַּר נָשׁ לְאִתְדַּכָּאָה, מְסַיְיעִין לֵיהּ מִלְּעֵילָא, וְסִיּוּעָא דְּמָארֵיהּ סַחֲרָא לֵיהּ, וְאִסְתַּמַּר וְאִקְרֵי קָדוֹשׁ.
