The blowing of the shofar on Rosh Hashanah is a powerful and inexplicable experience that transcends words and reason. It represents the ability to surpass ourselves and reach new heights. The writer compares the shofar to the dedication and commitment of his grandchildren serving in the army, who carry him to places unreachable by human words. The shofar symbolizes the need for humility and effort to activate its power, just as the Jewish people must activate their Jewish pride and commitment to live in a holy dimension. The writer emphasizes the importance of maintaining Jewish identity and unity in order to fight the enemy and fulfill the eternal mission of Judaism.
