Kuntres Mattan Torah, On the Completion of The Zohar

Complete attainment10. As we have already said, complete cleaving and complete attainment is divided into one hundred twenty-five general levels. According to this, we cannot attain all one hundred twenty-five levels before the Messianic era. There are two differences between all generations and the Messianic generation. The first is that only during the Messianic era can one achieve all one hundred twenty-five levels, unlike during all other generations. The second is that throughout the generations, only few exceptional people merited attaining and cleaving, as the sages have commented on the verse, “One man among a thousand I have found” (Ecclesiastes 7:28): “out of a thousand who entered a school… only one emerges who is capable of rendering decisions [pertaining to religious matters]” (Rashi and Kohelet Rabbah on Ecclesiastes 7:28), that is, of cleaving and understanding. But during the Messianic era, everyone can attain cleaving and understanding, as they have said, “for the earth shall be full of the knowledge of the Lord” (Isaiah 11:9), “and they shall teach no more every man his neighbor, and every man his brother, saying, Know the Lord; for they shall all know me, from the least of them to the greatest of them” (Jeremiah 31:34).
