I have been working with Ken, this is true. I have found him to be a natural adept; I leave him seated, sometimes in the morning, I come back, he has not moved an inch – he is completely absorbed in the mantra. I asked him what his experience was like, and he just stared at me, said nothing: obviously it is beyond the ability to verbalize at the shtula level. Pure transcendence. I even at one point stuck a pin in his foot and held a BIC lighter to his head – he did not flinch. Incredible. He is an amazing meditator.
