There’s a deeper secret about the necessity for each of us to have this negative inclination within us, however. Just as we could not exist without the positive desire, we also could not exist without that negative desire. The positive inclination that we have within us is an energy that gives us life, and so, too, is the negative inclination within us necessary to give us life. But how can we understand that we receive life from the negative inclination?
As we learned from Nadab and Avihu, if a person is truly involved in the spiritual work, is really growing in their connection, it is the nature of the soul to not want to reside in the body. That’s why, for instance, it says in the Tehillim, Book of Psalms, that with every breath we take, the soul wants to leave. The soul does not want to remain in this body, especially if it is awakened again to feel a connection with the Light of the Creator. We know it is the desire of everything to go back to its source, and the source of the soul is the Light of the Creator. As such, if there had not been a system built that almost forces the soul to stay within the body, the soul would leave the body all the time.
So, in order to stop the soul from leaving the body any time it senses the Light, the Creator took our essence, our soul, that positive nature which is really at the core of who we are, and enveloped it in the most negative desire, in the one thing that is exactly the opposite of the Light of the Creator: the Desire to Receive for the Self Alone. And what we call the negative inclination is, therefore, actually the protector. If not for the negative inclination that each one of us has, our soul would be out of our body.
The Negative Side isn’t there just to give us free will. Of course, that’s one of the reasons, but it’s also there to allow for life in the human body. Because if not for the fact that the soul was forcibly covered by this Desire to Receive for the Self Alone, the soul would not remain in the body. The Negative Side is always there to intervene and make sure that we don’t get too spiritual or connected; what happened to Nadab and Avihu, therefore, is that the protective layer of the negative inclination was broken.
With this understanding, we can begin to see that when we’re feeling disconnected, it is part of the protection, part of what keeps us alive. Any time we feel any type of lack, certainly a spiritual lack, what we’re feeling and connecting to is the protective layer that is allowing our soul to remain within the body. The soul, by nature, wants to go back to its source, so in order to allow us to do the work we need to in this world, the Creator gave us a gift that allows us to live: the negative inclination. It builds a layer, a shell, around the soul, and doesn’t allow it to connect 100% and completely get to the state where it wants to leave the body. Being enclosed within this negative inclination is what allows us to do the work in this world. It is truly a beautiful teaching, and gift.
