Personally, I always begin really to feel the “pull” of Shabbos each week on Thursday evening. That’s when it becomes real to me that Shabbos is almost here. My heart lightens and I feel hope and spiritual brightness. Shabbos is coming!
Sefirah is seven weeks. Each week is comparable to a day. The first week of Sefirah is comparable to Sunday/Yom Rishon; the second week to Monday/Yom Sheni. Lag B’Omer is the fifth day of the fifth week of Sefirah; in other words it’s comparable to Thursday evening. That’s when we feel Shabbos coming. We feel the pull of Torah. Torah becomes stronger than the material world; we begin to feel elevated.
As we approach Har Sinai, the pull of Torah becomes stronger and stronger. We have pulled ourselves out of the depths of Egyptian depravity. We have marched through the scorching and dangerous desert.
Lag B’Omer is here. Our hearts are turning to Hashem.
May His kindness soon overwhelm us and carry us all onward to Har Sinai.
