What are we supposed to be learning from the Rav’s many shiurim on the festivals [i.e. the Rav’s shiurim on Rosh HaShanah, Yom Kippur, Succos, Chanukah, Tu B’Shevat, Purim, Pesach, Lag B’Omer, Shavuos, Bein HaMitzarim, etc.] ?
The purpose of these shiurim [on the festivals] is to give an inner, deep perspective on each of the festivals. This deep analysis and perspective of the festival helps a person connect to and enter within, to some degree, the very essence of the festival. It can be compared to a person entering a perfume store, who enjoys the fragrant aroma there.
On a practical level, each person needs to be aware of his current avodah, according to his current level, before the festival arrives. One needs to know what his current avodah is right now, and how the coming festival can further illuminate one’s personal avodah as of now. However, one should not digress from one’s current avodah and begin a different avodah.
