I heard some tremendous Chizuk from Rabbi Efriam Wachsman in a shiur titled "Megilas Esther: Discovering the Depths of Our Neshomos":
(Note: In general, Rabbi Wachsman's shiurim often give chizuk to those who struggle with the Yetzer Harrah.To hear his Shiurim, call the Yeshiva at 845-426-3488. There is an extension for the tape and CD library.)
The Rizhiner explains that in one way, Purim is greater than Yom Kipur (Yom Ki- Purim. A day that is only "like" Purim, but not as great).
Yom Kippur atones for the Shavim (Those who return - i.e. repent), while Purim atones for the Shavim and the Aino Shavim (those who return and those who do not return).
What does it mean that Purim atones for the Aino Shavim, those who do not return?
The Rizhiner explains that Purim is a holy day for those who repent but yet continue to fall. They are labeled "Aino Shavim" because they continually have to face their struggle. Purim is all about seeing the light in an atmosphere of total darkness. It is about seeking out Hashem even if we feel we are in total darkness and may be feeling ashamed or low. Hashem says "Anochi Hastir Astir Panai ("I will utterly hide my face from you"), yet in that same pasuk is the remez (hint) to Esther , our salvation. Hashem rejoices when we reach out to him, and when we rejoice in our effort to seek Hashem out.
GYE is about seeking out the light in the dark world around us. It is about confronting struggles that have plagued us for years. We may have continued to fall many times, yet we - as a family - are seeking out the light to overcome our addictions. We are finding Hashem in the darkness. That is the true holy essence of Purim, and that is why Purim is the happiest day of the year.
May we all tap into the holy day of Purim. May we all find Hashem in the darkness. May we all have extra Siatah Dishmayah to overcome our illness and may we all rejoice in re-discovering ourselves.
