The fact that the symptom of tzara’at was a white spot on the flesh indicates that tzara’at resulted when holy rapture is not balanced by an equal sense of humble commitment to our Divine mission. Divine rapture is an expression of our love of G‑d, whereas humble devotion to His will is an expression of our fear of G‑d and submission to His will. Love of G‑d and fear of G‑d are identified in Jewish mystical texts as the “right hand” and “left hand” of our soul, respectively. Thus, favoring one over the other upsets our spiritual balance.
Opposite forces can only be harmonized by using a third force that surpasses and encompasses them both – the study of the Torah. Studying the Torah with a sense of self-nullification to G‑d enables us to rise above the limitations of logic and nature. We can harmonize the opposites of love and fear, and restore the healthy balance between them. This is another way in which the study of the Torah is the antidote for gossip and slander, bringing healing and harmony into the world.1
To my understanding, it is pertinent to make a distinction if we want to understand properly this Spiritual Balance. The focal subject is that one suffering from tzara'at. Not those who are good and healthy ones. Like those who practice gossip and slander. There are many people who have never had access to the Torah. How supposedly are they going to get rid of their tzara'at? First choice is to openly admit it: Yes, I'm plagued with tzara'at, so what? Am I going to be a segregated? I'll join others like me. Second choice is to conceal that tzara'at, no problem in hiding a white spot and at the same time praying merciful G-d to stay me above the tongues of gossips and slanderers.
