The correction of broken desires happens step by step, thanks to the actions of the Upper Mother (Ima Ilaa), Bina of the world of Atzilut. A very complicated system works there, and it allows the influence to eventually reach the souls. However, behind all of this there acts the Light of Hochma dressed in the Light of Bina, which corrects desires, the fragmented souls.
When we pray, reaching out to the Light of AB-SAG, meaning the Light of Hochma dressed in the Light of Bina, we glorify its beauty (“beauty” in Aramaic is “Shufrah”). This is why there is a tradition to blow a special horn called a Shofar at a New Year celebration.
By doing so, we praise and proclaim the Creator’s governance, that is, the supremacy of the force that controls and leads us, the Light of Hochma dressed in the Light of Bina, which is called beautiful. The Light of Hochma (wisdom, beauty) manifests itself in us to the degree of our aspiration to acquire the property of bestowal (Bina). It’s considered the beginning of man (Adam), the one who strives to become similar (Domeh) to the Creator.
This explains why a Shofar symbolizes a New Year: It glorifies the reign of the upper force; it is our request for the Light of AB–SAG to come, to correct us, to fill, and to raise us by the ladder of correction to the upper King. All corrections that we anticipate to happen in the New Year are gathered in one day called the “head of the Year” (Rosh Hashanah) since potentially it already contains the tendency that we would like to practically implement during the year to come.
