וְהָיָ֗ה אִם־שָׁמֹ֤עַ תִּשְׁמְעוּ֙ אֶל־מִצְוֺתַ֔י אֲשֶׁ֧ר אָנֹכִ֛י מְצַוֶּ֥ה אֶתְכֶ֖ם הַיּ֑וֹם לְאַהֲבָ֞ה אֶת־יְהוָ֤ה אֱלֹֽהֵיכֶם֙ וּלְעָבְד֔וֹ בְּכָל־לְבַבְכֶ֖ם וּבְכָל־נַפְשְׁכֶֽם׃
내가 오늘날 너희에게 명하는 나의 명령을 너희가 만일 청종하고 너희의 하나님 여호와를 사랑하여 마음을 다하고 성품을 다하여 섬기면
Noam Elimelekh
And the second level "Service" - this is the Prayer that is the center of the service of the heart as they said "and to serve God with all your heart, this is Prayer [Tefilah]" (Taanit 2a), because the heart understands and with [Prayer] it can rise to clinging to the Creator and tie itself to the Blessed One, since Tefilah comes from the expression knot/connection, to cling oneself to the Blessed Creator with a great clinging, and this hints to the knot of the tefilin of the hand to tie the thought in one's heart to the High One, and for that one needs more effort to always pray to the Holy Blessed Name that God will help that one's yetzer hara [inclination for evil] will never be separated from clinging to the Creator, because the nature of a person is that one is likely to turn [at any moment] his thoughts to the issues and preoccupations of this world.
