The reason hypersigils are so misunderstood is that Grant’s hypersigil defintion is badly explained to the point of causing more confusion than insight.
As i’ve said before on this board, the hypersigil originated with Dr. Milton Erickson in America, and Dr. Vladimir Raikov in the Soviet Union, both of whom discovered it independently of each other in the late 60s and early 70s. It’s an inner circle NLP technique you rarely hear spoken of, but the top performers use it to transmit high-level performance skills via teacher-student possession rituals.
A more useful and more adaptable version of Grant’s technique is found in John Overdurf’s Deep Trance Identification manual, with multiple variations covering all possibilities.
