Disturbing Ad

I saw an ad in the new Health Section of Mishpacha with R' Michel Twerski's picture in which he promotes [I was going to say the name of the System, but decided not to advertise it] for mental well being.  I wrote a letter to the magazine saying this is disturbing when LP, wife and business partner of GP, who teach and promote the System says, “No thoughts are true, no experiences are true, the principles [of their System] are the only things that are true.”

I asked, if that isn't kefira, what is?

This is the basis for the System which is sourced in Buddhist philosophy. The frum proponents of this System, like R' Michel Twersky etc. try to avoid the kefira aspect, but it's there.
