Link to Birthday of the World

* "It was a custom of the Gaon of Vilna to be very joyful at this time when the shofar was being sounded, for he maintained that just as we are so joyful when a new king is coronated, so too on the day of Rosh Hashanah, when we coronate Hashem as our King, we must rejoice in full measure." pg. 25 of Sho'or Yoshuv Institute's "The Commentator's Machzor Companion".
