Wait are we talking Harry Potter or Tony Robbins?
So technically an incantation is defined as a series of words said as a magic spell or charm. I suppose I agree to an extent.
I first learned of incantations from a Tony Robbins audio I was listening to. He was discussing his pre-seminar ritual and how, for many years, he had been using incantations to both mentally and physically prepare himself to walk out on stage and deliver.
