קבלה על ישעיהו 2:3

65 And it is the same for his children after him as well, for if they want to grasp this, and to establish this idea in their souls from the approach of wisdom - that would be enough, for they only need only to know it, and they do know it, and when it becomes clear - it becomes clear. But since man is not meritorious through his acts, and just the opposite, follow after the deceit that is apparent to their face with all the poor ideas that we mentioned above, behold the Holy One blessed is he needs to reveal to them that which they were unable to grasp. And this is only through the way that he does in this exile, where he has hidden his countenance in concealment after concealment, until negativity has been strengthened in the world - the purpose of great strengthening; and as the Rabbis may their memory be blessed (Sotah 49a, see there), "There is no day whose blessing is not greater than another". And behold, in the end of it all - suddenly he will come to his sanctuary, of the singular master blessed is he, and the glory of G-d will be revealed and will be seen by all together:

66 And that which is now because of the significant concealment of His countenance, wisdom has been diminished and actions have been damaged, and as s consequence to this all of the creations themselves have been damaged and diminished, as they said (Sotah 48a), "...the taste of the fruit has been taken...", and all the the other negative things that our Rabbis may their memory be blessed have told us, and which we see with our own eyes - behold the land is chaos, and like their saying may they be blessed (Sotah 49b), [in the time before Mashiach], brazenness will increase and prices will increase...", for all of this is the strengthening of great negativity, behold when the glory of haShem will be revealed - all wisdom will return to the straight path, and all actions will be restored as at the beginning, and people will cleave to their creator, as it says in the text (Joel 3:1) "I shall pour out my spirit on all flesh..."; and similarly (Jeremiah 31:33), "And man will no longer teach is fellow...to say know haShem, for all will know me from the small among them to the great"; and it will be that the general passion for the whole world will be to made holy with His holiness may He be blessed, and like the matter that says (Isaiah 2:3), " And the many peoples will travel and say let ups go and ascend to the mount of HaShem...and he will instruct us in his path and we will follow after him...". And born from this will be all the successes of the creations, as the matter that is said (Psalms 72:16), "Let abundant grain be in the land on the tops of the mountains...."; (Isaiah 11:6) "and the wolf will dwell with the lamb...":
