Musar sobre Isaías 51:16

And the world endures only through Torah, as it is written (Jeremiah 33:25): "If not for My covenant, day and night, the statutes of heaven and earth I would not have ordained." And this is the language of the holy Zohar, Parshath Bereshith 47a: "Everyone who occupies himself with Torah every day will merit having a share in the world to come, and it will be accounted to him as if he had built worlds. For it was through Torah that the world was built and fashioned, as it is written (Mishlei 3:19): 'The L-rd, through wisdom [Torah] founded the earth, etc.' And everyone who occupies himself with it shapes the worlds and sustains them. And come and see: It was with a spirit that the Holy One Blessed be He made the world, and it is with a spirit that it endures, the spirit of those who toil in Torah." And this is the language of Parshath Tzav: " R. Elazar opened and said: (Isaiah 51:16): 'And I have placed My words in your mouth, and with the shadow of My hand have I covered you, etc.' From here we learn that if a man occupies himself with words of Torah and his lips murmur Torah, the Holy One Blessed be He hovers over him and the Shechinah spreads its wings over him. What is more, he causes the world to endure and the Holy One Blessed be He rejoices with him as if the heavens and the earth were planted on that day."

(Sanhedrin 99b): “R. Yochanan said: ‘He [one who learns Torah] also secures protection for the entire world, viz. (Isaiah 51:16): “and with the shadow of My hand have I covered you” [and, consequently, the entire world].”’” Levi said: ‘He also brings the redemption nearer, viz. (Ibid.): “and to say to Zion: ‘You are my people.’”’”

Each and every Torah insight that a person reveals ascends On High and stands before the Holy One Blessed is He. The Holy One Blessed is He kisses it and crowns it with several crowns, creating from it a new heaven and a new earth. These then stand before Him in order that His eyes may be upon them continually to watch over him personally by means of them. And in order that the ministering angels not be jealous of him, the Holy One Blessed is He covers over and conceals those insights until He has fashioned from them the new Heaven and the new earth. This is what is meant by the verse, “And with My hand I have covered you to plant heaven and to found the earth” (Yeshayahu 51:16). But this applies only if he does not become conceited over his learning and the novel insights he has revealed, Heaven forbid, as the Zohar teaches in Parashas Terumah (129a):
