Zohar Ki Tetze
“כִּי-יִמְצָא אִישׁ, נַעֲרָ בְתוּלָה אֲשֶׁר לֹא-אֹרָשָׂה, וּתְפָשָׂהּ, וְשָׁכַב עִמָּהּ; וְנִמְצָאוּ.”
“If a man finds a girl who is a virgin, who is not engaged, and seizes her and lies with her and they are discovered,”
The Torah commands the person that forced himself onto a virgin, to marry her. He is commanded to pay her father and is forbidden from sending her away all his days.
The Zohar reveals from this verse a secret of the reincarnation process. The virgin is a pure soul that was forced to be part of a sin. If the soul was found with sins after death then it must stay in the same process in the life until the soul is purified.
