Ive heard that Jews aren supposed to study Kabbalah until they e at least 40. Does anyone still follow that rule?
It was never a hard-and-fast rule, it was simply one tradition. Age 20 was good enough for many teachers, provided the students had attained a sufficient level of learning about the Torah and the Talmud and seemed mentally and emotionally stable. Nowadays, it’s up to the teacher. I’m sure there are some ultra-orthodox teachers who follow the 40-only rule; others believe that even children can benefit from exposure to Kabbalah principles.
