A posek who regularly consults with R’ Elyashiv told me when I told him I heard R’ Elyashiv say something-
“Half the things that R’ Elyashiv said… he never said.”
I’m assuming the same would be true for R’ Chaim. I really find this VERY hard to believe and I’d just like to echo the need to speak to your Rav before doing anything at all.
BTW in regards to mekuballim, be very careful that you are dealing with someone who is legit. There are a lot of “mekuballim” who are dabbling in Kochos hatumah. My rosh yeshiva told me that any mekubal should be able to explain to you any tosfos in shas on the spot because if you really know kaballah you have to know kol hatorah kula. See faith and folly by R’ Yaakov Hillel.
