Likutei Moharan 47:5/ליקוטי מוהר"ן מ״ז:ה׳

15. Thus when we eat the true bounty that comes by way of the Land of Israel, and afterwards with that strength recite the praise of the Holy One, then heaven and earth are made anew. As our Sages taught: “saying to Zion: ‘You are My people’” (Isaiah 51:16) —do not read this ami (My people) but imi (with Me), in partnership with Me (Zohar I, 5a). For the new heaven is made by means of the illumination of Yaakov’s face; and the new earth is made by means of the Land of Israel, because the influx of bounty goes by way of the Land of Israel.

2We find then that he has now created another heaven and other constellations. He has consequently changed the [course of] nature impressed into the original constellations, which have now become new constellations. Thus it is that by breaking the desire for eating, miracles and wonders are made.
