Love independent of deed[1]
ביום שביעי שהוא הושענא רבה נוהגים להרבות במזמורים כמו ביום טוב וכו’ ונוטלים ערבה ביום זה מלבד ערבה שבלולב
On the seventh day [of Sukkos], which is called Hoshana Rabbah, the custom is to increase in Psalms, like we do on a Yom Tov…and we take a willow branch on this day, besides the willow found in the four species[2]
The last day of Sukkos is one of the strangest days of prayer on the calendar. It is known as Hoshana Rabbah. On the one hand, it’s still Sukkos, so we shake the four species. Like the other days of Chol HaMoed, it’s like a weekday in that some creative work is permitted[3], and some even wear tefillin. However, it’s not like the other “weekdays” of Sukkos. We add extra prayers, those that are usually only said on Shabbos and Yom Tov. Tunes from the High Holidays are used. A lot of literature has been written on Hoshana Rabbah, likening it to Rosh Hashana and Yom Kippur.
