Holy Zohar text. Daily Zohar -351.

Tikkun 21 – 92

The Shofar that we blow on Rosh Hashanah breaks our negativity and removes judgment from ourselves. It is also the supernal tool from the level of Binah that will break and remove all negativity from the world.

Isaiah 27:13
“ וְהָיָה בַּיּוֹם הַהוּא, יִתָּקַע בְּשׁוֹפָר גָּדוֹל, וּבָאוּ הָאֹבְדִים בְּאֶרֶץ אַשּׁוּר, וְהַנִּדָּחִים בְּאֶרֶץ מִצְרָיִם; וְהִשְׁתַּחֲווּ לַיהוָה בְּהַר הַקֹּדֶשׁ, בִּירוּשָׁלִָם”
“And in that day a great Shofar will be blown, and those who were lost in the land of Assyria and those who were driven out to the land of Egypt will come and worship YHVH on the holy mountain at Jerusalem”

This is the secret of the Cantillation

Also the cantilation that relate to the final redemption.

At the time of the final redemption all negativity will be removed from existence.
This will fulfill the prophecy of Isaiah 25:8 “ בִּלַּע הַמָּוֶת לָנֶצַח” “Death will be swallowed forever”, The prayers will ascend in 4 types of songs. Simple song, which is for the letter Y of YHVH and the Sefira of Keter , double song for YH, Chokmah and Binah, Triple song for YHV, Chessed , Gevurah and Tiferet, and quadruple song for YHVH, Netzach , Hod, Yesod and Malchut.
That connects all the 10 Sefirot together as one bridge from our world of action to the spiritual world.

King David used 10 types of Psalms to give us the connection to the ten Sefirot to help us remove negativity from our lives.
