Chasidut zu Tehillim 31:20

And now, blessed are you by God, oh sweet reader. Be enlightened and understand that on this day began the revelation of the goodness of the Torah within which was hidden “the light that was good,” that light which allowed Adam to see from one end of the world to the other, and through which we can see the mysteries of the Creator. R’ Shimon bar Yochai was called “the holy lamp” because through him were revealed the secrets of Torah, that is the secret of “the light that was good” which is hidden in the Torah. Therefore his holy book is called the Zohar (lit. brilliance), meaning a light which shines from one end of the world to the other – the ‘good light’ which is hidden away in the Torah. That is why this day is the best of days for the giving of Torah. This is when the good light in the Torah began to shone forth, as we have learned. And this day is the 33rd day of the Omer, Lag Baomer. This is the day of the hilulah (lit. rejoicing) of R’ Shimon bar Yochai, the very day on which he ascended to the highest heavens. It also makes sense to assume that he was born on this day as well, because the Holy One sits and completes the years of the righteous from day to day (Kiddushin 38a). The very day on which ‘the light that is good’ began to shine out from the Torah, that is the best of days before the giving of the Torah, is the very day on which the holy soul that would reveal the path of ‘the light that is good’ in Torah was itself revealed. That is why this holy soul was called “the holy lamp,” on the very day that he rose up to the highest heavens he commanded R’ Aba to write down all the storehouses of hidden knowledge which he had revealed in order to leave behind a blessing from the illumination of the hidden light (that is good, as it says “How abundant is the good that You have in store for those who fear You…” (Psalms 31:20)) It is preserved there for us and our children until the light of our righteous Messiah is revealed, speedily and in our day! It is as our Sages said “And God said, let there be light…” this refers to the light of the King Messiah (Pesikta Rabbati 36), in the merit of our occupation with ‘the light that is good’ which the holy lamp left behind as a blessing and life, and a light for all Israel.

Fortunate is the person who listens to these words, to fulfill all that is written herein. He will never slip (based on Psalms 112:6) and his righteousness will answer for him in the time to come (based on Beraishis 30:33), when he comes to receive his reward. In the measure that a person meets out -- so (In that same measure) is he met with. Fortunate is one who chooses life -- Hashem will repay his endeavors, if it is to scoffers He will scoff (Proverbs 3:34), he will not gain wealth and his wealth will not endure (Job 15:29), woe to his soul -- for the retribution of his handiwork will be done to him (Isaiah 3:11), it will not be cast to the ground (but on their heads -Job 15:29), one who is good before G-d will escape from it (Ecclesiastes 7:26). How great is the goodness hidden away for him (based on Psalms 31:20), in his joy no stranger will take part (Proverbs 14:10), a laboring soul benefits from its labor (Proverbs 16:26, see also Tractate Sanhedrin 99b -- he works here and his Torah works for him elsewhere). Let us pour out our souls to Hashem to put our portion with Him, to stand at the threshold of His shade, they will have no regrets -- those who put their trust in Him (Psalms end of Chapter 34), no eye has seen (their reward) except for You G-d, what He will do for those who put their hope in Him (Isaiah 64:3).

When the Red Sea split the hidden form of evil crumbled. Rabbi Isaac Luriah explained that the splitting of the Red Sea and the revelation of a dry sea floor represented an emergence of the Alma De-Iskasya, “the hidden world.” The waves of an ocean are always visible and they represent the revealed dimension, while the sea floor that is usually covered with water represents the hidden realm. Apparently, when Jewry arrived at the Red Sea, we found our inner voice of virtue, we revealed our Rav tuvcha asher tzafanta le-yereacha, “the great amounts of Your good that are hidden away for those who revere you” (Ps. 31:20). We revealed yechidah, and then the hidden evil force that had broadcast anti-Jewish hate and sin collapsed.
