In both lessons this past Shabbat at Chut Shel Chessed, Rav Shalom Arush spoke about the power of Rebbe Shimon Bar Yochai. He said that Lag BaOmer is a very great day and on it one can accomplish very great things if they put in the prayer. He said that this day is opportune to achieve both spiritual and physical salvations. Even if one cannot make it to Meron, the day itself is extremely holy and one can pray from any place they may be. Just light a candle and ask Hashem for all your needs in the merit of Rebbe Shimon.
He also gave over a very nice idea on how Rebbe Shimon came to his greatness. He said that the entire time that Rebbe Shimon and his son were in the cave, they were happy and accepted G-d's mishpat (judgement) with love. Similar to how Yosef HaTzadik was in prison for 12 years and also accepted it with love. Many of us have difficulties and challenges, but if we are upset about them, than it is the same as if we are saying to Hashem that we do not agree with His judgement. Instead, one should first strengthen their emuna and know it is from Hashem and good, and then one can reach very high levels specifically because of the difficulties.
The Rav also spoke about holiness, specifically guarding the eyes. He said that holiness is the main difference between us and the nations and there is no protection for the Jewish people unless we have holiness, as we learned from the stroy of Bilam. He also said that a man who guards his eyes or a woman who dresses modestly is protected personally by Hashem and has nothing to fear in this world.
Don't forget to read some Zohar, and know that the world right now is in huge need of protection from many many judgements. If you want proof just read:
Rebbe Shimon is fitting to be relied upon in a time of great need and with his sefer (The Zohar) we will be redeemed from this exile with mercy, amen.
