27 Teves: The Infinite Body
THE INFINITE BODY
R. Yehoshua ben Chananya said, ā[In the time of the resurrection,] G-d will regenerate the body from the luz bone of the spine, [which is indestructible.]ā To demonstrate this, he put it through a grinder, but it was not crushed. He placed it in fire, but it did not burn. He soaked it in water, but it did not dissolve. He placed it on an anvil and struck it with a hammer. The anvil cracked, and the hammer split, but the luz bone was unaffected. (Midrash Rabbah, Bereishis 28:3)
G-d chose not only the souls of the Jewish Nation, but He also chose their bodies. This choice affects even the physical nature of the body, imbuing it with G-dās infinite ability. The luz bone is a physical expression of the infinite nature of the body itself.
Like the luz bone, our G-dly core is immutable. With it, we can accomplish anything.
Tanya, Ch. 49
