>>>what does Gemora in the second perek of Chagigah say about learning pnimius Ha�Torah? Who is supposed to be doing it? Every last dimwitted individual?
Indeed, the Gemara their said that the secrets of the Torah most only be given over to ?? ???? ???? ?????.
This is why for many years kabbala was only learned by a select few and kept a secret (which is why it is called ??? ????).
However, as we get closer the Geula, the process of revelation has already begun. As the Arizal said (written by his student ?’ ???? ?????): ???? ?????? ??? ???????? ???? ????? ????? ??? ?????
Additionally, chassidus is not pure kabbala (although it is based on many ideas in kabbala), rather it is explained by the rabbeim in a way that can be understood by everyone (if learned properly, with the right guidance).
As the Rebbe Rayatz wrote:

Here is also an interesting letter from the Rebbe on the matter, in response to someone who was worried about learning chassidus due to the problems with learning kabbala:
