זוהר שמות — דף צז ע”ב

This section concerns the reward of the soul that has fulfilled its mission in this world, with the promise that the Holy One will prepare for it a hidden deed in the world to come, « what no eye has seen ». The elder prays and weeps, raising the question: is the soul that returns at the end the same soul that fulfilled the world, or another one? The Zohar explains that it is the very same soul, but with an added increment of light and higher holiness bestowed upon it.
