זוהר שמות — דף ק ע”ב

The Zohar addresses the verse « many of those who sleep in the dusty earth shall awaken » and its implications for souls that did not merit correction. Admat afar refers to the dimensions of yesod and tevel, and these are the souls that did not merit correction. But if that naked spirit merits to return and be corrected, it is righteous and is rectified in that first body. The Giborim are those whose naked spirit remained and was drawn into another body.
