On Lag B’Omer we celebrate the passing of the great Kabbalist, Rabbi Shimon Bar Yochai, author of The Zohar. He was a special person and the revelation he made signifies the giving of the Torah, the science of correction, to the whole world.
Humanity developed from one generation to the next in birth pangs until it reached Abraham, who revealed the science of Kabbalah above the crisis that developed in Ancient Babylon. Then the nation of Israel waited for the Egyptian slavery and the Exodus from it, followed by the construction of the First and Second Temples, as well as other ascents and descents. All the horrible events that befell this nation and all human history in general appear to be one never-ending trial.
However, the entire path that we went through until the arrival of Rabbi Shimon was just our preparation for correction. After the destruction of the Second Temple, the nation of Israel finally lost the sensation of spirituality and entered exile from it. But then we received this gift from the heavens, marked by the arrival of a sage from the times of the Temple (a Tana), a Kabbalist of great stature. His special soul incorporated all the previous souls and united them within itself. That is why, together with his students, he was able to attain an extraordinary height, the final correction in his generation.
Baal HaSulam writes that never in history has there been any attainment higher than the one achieved in the times of Rashbi and his generation. The likes of it can only happen again at the End of Correction, and we are now standing at its threshold.
Zohar is the name of the Light that becomes revealed in GAR of the World of Atzilut, in its root, which is a special place – the "concealed mind" of the system of Arich Anpin. Rabbi Shimon was unique in that he was able to connect this incredibly high level with our world. His attainment placed him on the level of the Final Correction, just as before the destruction of the Temple, yet at the same time, he lived a regular, material life in the times after the destruction of the Second Temple. This was when the nation fell completely from the level of brotherly love to unfounded hatred, and this fall caused a complete disappearance of the spiritual sensation.
Because Rabbi Shimon united these two entirely different poles within him, he was able to write this great Book, meaning to make a revelation. Without it, we would not have the opportunity to correct our souls and attract the Light that Reforms.
