Daily Zohar – Tikunim – #313 – The chant of purity
Tikkun 21 – 54
When the Shechinah is in exile, meaning away from the Light, it creates a state of suffering to the Tzaddikim. They work hard in their connection to bring her closer to her husband, the Holy One Bless be He.
With this unification the Shechina receives the light that the Tzadik channels through the purity of his actions at the level of Yessod.
The cantillation of Pazer Gadol represents this connection. The revelation of pure seeds of light brought about the establishment of Zarka to bring the light of Binah.
