Whoever opens The Book of Zohar finds that the first correction we must carry out is to obtain true fear.
People usually experience two types of fear: of this world (health, wealth, children, etc.) or of the next world (preparing themselves for heaven rather than hell).
The process of spiritual development introduces us to a third type of fear—the true fear—whether or not we will succeed in resembling the Creator and attain the quality of love and bestowal toward others and toward Him.
The study of Kabbalah develops within us the perception of the unity of everything and shifts the corporeal fears to true fear.
