Answer: The study of Kabbalah does not require any special mental abilities because it is not learned with the mind. On the contrary, people who consider themselves smart, who are good at studying, who grasp things quickly and have a keen mind, usually do not advance very well in Kabbalah. That’s because the mind and the sensation of their mental abilities stops them, carrying them away to the path of the rational study of this science instead of attaining it by being loyal to the group. This is a problem.
I would say that it’s precisely the regular, “average” people who are more successful in spiritual advancement. The brilliant smart-alecs who come to study the science of Kabbalah usually stumble right away. I see that its as if they jump head-first into the deep sea, and “resurface” from there many years later, once the water washes off all of their pride, feeling of superiority, and power.
Let us hope that we belong to those who are successful in attainment rather than those who have a brilliant mind.
