The code for cracking the encrypted texts in the wisdom of Kabbalah must be constructed inside a person. We must awaken from the egoistic desire of receiving for oneself to the desire of the Creator, which is to express bestowal and love for others. There had been intense opposition to the revelation of the wisdom of Kabbalah in the period of Hasidism and the Lithuanian Mitnagdim (those who opposed Hasidism). Rav Kook and Baal HaSulam attempted to make the wisdom public in the beginning of the twentieth century. The Ari also understood that the time had come to reveal the power that is concealed in the Torah and reach the summit of the evolution of the created beings.
