Well some people cannot be hypnotized.
If I was ever hypnotized I would personally be very disappointed in my spiritual practice, though my practice is little and I have no accomplishment. Life itself seems to hynotize us, working against this self hypnosis is ongoing it seems and a part of some peoples spiritual practices.
So this will probably never happen but if I did meet a hypnotist daring to hypnotize anyone....I would gladly take that challenge, and see if they may.
"This order considers that progress can be achieved more rapidly during a single month of self-transformation through terrifying conditions in rough terrain and in "the abode of harmful forces" than through meditating for a period of three years in towns and monasteries"....Takpo Tashi Namgyal.
