Korach hoped to change everything that was in his egoistic nature to bestowal.
Comment: Isn’t being the Pharaoh’s treasurer a negative trait?
Answer: On the contrary, he was smart! Someone who is smart is not considered a wise person; rather, it is someone who knows what to do with his intelligence.
So to be “the sole manager of the royal treasury” means to take on the task of transforming acts of reception into bestowal. This means attaining the end of correction (Gmar Tikkun) by transforming all the wealth of the ego into bestowal.
In spite of his exceptional characteristics, Korach never dared to confront Moses, but his wife constantly elevated her husband’s self-confidence and convinced him that he was not inferior to Moses and Aaron in any way. Unfortunately, Korach listened to her words.
Here the same thing that happened to Adam HaRishon (the First Man) repeated itself. The “serpent” did its job.
The woman is the desire to receive within us, and this desire says to you that you can do more and for this you don’t need to be connected to Moses. And Moses is the characteristic of pure Bina.
So when Korach became detached from Bina, he could no longer deal with the royal treasury, because the treasury refers to the egoistic forces that are possible to gradually transform into altruistic ones.
