Baal HaSulam, “Introduction to The Book of Zohar,” Item 3, Inquiry No. 5: The matter of the rising of the dead: Since the body is so contemptible, that immediately at birth it is doomed to perish and to be buried. Moreover, The Zohar said that before the body rots entirely, the soul cannot ascend to its place in the Garden of Eden, while there are still remnants of it. Therefore, why must it return and rise at the revival of the dead? Could the Creator not delight the souls without it?
Indeed, why should “the body” be revived? What about the soul? Will it come down from Heaven again?
Even more bewildering is what our sages said, that the dead are destined to rise with their flaws, so that they will not be mistaken for another, and after that He will cure their flaws.
Nothing remains of the body after it rots. So why does it have to revived? What difference does it make if someone says something?
We must understand why God should mind that they would not be mistaken for another, that for that He would recreate their flaws and then would have to cure it.
“A body,” which means the desire to receive, has always been holy and has always been in adhesion. The whole round we make is necessary only in order to rise higher towards the Creator so that we will feel all the 125 degrees, so that we will have the fineness and the sensitivity and will clarify and sharpen our perception in feeling the Creator, and will rise from the level of the created being to the level of the Creator by ourselves.
Therefore, the desire to receive has to go through this whole cycle and at the end of correction to come back and acquire all the flaws. Then we will be able to compare what it was at the beginning of creation and what it has become at the end of creation after it has been through all the levels and has rotted.
All this is fulfilled by our work at the end of which, after the “rising of the dead,” we acquire a new discernment of the desire and by it can adhere to the Creator.
