An elderly JW once told me yrs ago (and now I believe it) that the WA form of meditation is self hypnosis. At the kingdom halls there is the constant buzzing of the microphones and equipment, the speaker droning on, the question and answer period where your eyes move back and forth at a constant pace.
At home you are told to meditate on the WA literature, again, staring at something or closing your eyes and visualizing statements in the WA. All are self hypnosis techniques.
So if you are facing illness and death, meditating on the resurrection will get you back under the society's control five times per week. That's why no Sunday mtg and that's it. Its five meetings per week to constantly enforce the WA doctrine and enforce the hypnosis.
This study I think is proof of how deceitful and cruel the GB is. JWs have died due to WA policies, not because of what Jesus taught in the scriptures.
