There are people in our world who are hardhearted, stubborn, and set in their evil and selfish ways. The Zohar describes these people as refusing to change the negative aspects of their natures. They seek not to embrace the path of spiritual transformation and the Light of the Creator. All of us, to a certain degree, possess an aspect of these negative traits.
The power available to us through these verses cleanses away negative qualities from our essence and being. The Light flowing through this portion helps to soften our resolve in situations where our stubbornness and ego prevent us from embracing spiritual change. The verses arouse a desire to seek a true connection to the Light of the Creator.
