Proof that Our Generation Has Reached the Days of the Messiah
Rashbi and his generation, the authors of The Zohar, were granted all 125 degrees in completeness, even though it was prior to the days of the Messiah. It was said about him and his disciples: “A sage is preferable to a prophet.” Hence, we often find in The Zohar that there will be none like the generation of Rashbi until the generation of the Messiah King. This is why his composition made such a great impact in the world, since the secrets of the Torah in it occupy the level of all 125 degrees.
Hence, it is said in The Zohar that The Book of Zohar will be revealed only at the End of Days, the days of the Messiah. This is so because we have already said that if the degrees of the students are not at the full measure of the degree of the author, they will not understand his intimations, since they do not have a common attainment.
And since the degree of the authors of The Zohar is at the full level of the 125 degrees, they cannot be attained prior to the days of the Messiah. It follows that there will be no common attainment with the authors of The Zohar in the generations preceding the days of the Messiah. Hence, The Zohar could not be revealed in the generations before the generation of the Messiah.
