The barrier above we shoot through with our prayer is a מסך המבדיל, an iron curtain we create through our sins.
It says in Yeshayah 59
ישעיהו פרק נט פסוק ב
כִּ֤י אִם־עֲוֹנֹֽתֵיכֶם֙ הָי֣וּ מַבְדִּלִ֔ים בֵּינֵכֶ֕ם לְבֵ֖ין אֱלֹהֵיכֶ֑ם וְחַטֹּֽאותֵיכֶ֗ם הִסְתִּ֧ירוּ פָנִ֛ים מִכֶּ֖ם מִשְּׁמֽוֹעַ
Your sins create a separation from you and between your G-d, and your sins turn away the face from listening.
Asks the Binah Leitim two questions:
It should have said between you? it should have also said, Hashem’s face from listening?
Explains the Bina Leitim that besides creating through the sins an iron curtain separation from Hashem, we are also creating a separation among us. The second question is telling us that through our sins, not only Hashem doesn’t listen to us, but we end up not listening to Him.
This can be demonstrated visually by us being around a circle and Hashem is in the middle. Our purpose in life is to through the love for each other, make the circle smaller by uniting the points on the circle, getting closer to the center and eventually becoming one with the center. So, the bigger the circle is, the further we become from the center. The Shlah Hakadash explains the pasuk in Iyav 23
איוב פרק כג
וְה֣וּא בְ֭אֶחָד וּמִ֣י יְשִׁיבֶ֑נּוּ

If He is in One who can dispute Him.
It should have said One not in One? So he explains that we become kavayochel one with Hashem meaning together, in one with Hashem.
