Tikkun 21 – 52
The movement and vibration of the Ravia cantillation elevates Malchut to Zeir Anpin. After the elevation, it transforms to Zakef Gadol , meaning high erection. This is because it goes up the two columns of Chessed and Gevurah.
The word Gadol, meaning great, is here to reveal the connection to Chessed as King David said in 1 Chronicles (29:11)
“לְךָ יְהוָה הַגְּדֻלָּה וְהַגְּבוּרָה וְהַתִּפְאֶרֶת, וְהַנֵּצַח וְהַהוֹד”
“To you, YHVH is the greatness, and the power, and the glory, and the victory, and the majesty;”
When the movement comes down, it is Zakef Katan and its light is revealed in Yessod.
When the sound ascends with the chant of the Ravia it is done with the right column. It is the aspect of Tekiah sound of the Shofar.
The light is drawn down using the Tavir cantillation through the right column of Chessed. It is the aspect of the sound of Shevarim of the Shofar blowing. It restricts the left column with balance to reveal the attribute of “ארך אפים” ” Long-suffering” from the 13 attributes that is in the central column.
