This week begins the six week period of Shovavim, a time period that the Arizal wrote is an auspicious time to work on oneself, especially in the areas of sexual transgressions.
I have two questions:
Is the Arizal the originator of this idea? Or did he already have a Mesorah for it? If so, what is the earliest source for this idea
If the Arizal was the originator of this idea, is it historically documented that the people who lived during his time period struggled particularly with sexual sins?
