He is in essence your very self. Return to Me, since all things seek the source of their beginnings. When you return to me in Teshuva h, you bring about unification of the Jewish people. With trumpets and with the voice of the shofar you shall blow before Hashem your King. The Great Maggid of Mezritch explained that the two trumpets were made out of one piece of beaten silver.
Silver is kesef, which means to long for or desire.
They represent the longing of the soul to return ans reunite with its source. The two trumpets are blown and the sounds unite in harmony, symbolizing the reunification of the soul which had been rent asunder from its source. Plain and simple it is true. Through Teshuvah the soul is reuntied with it source at the Throne of Glory. The Holy Zohar refers to the Supernal aspect of G-d as Shoshana , a rose.
