I think that a weird thing that some BSP therapists do if they haven't had enough experience in the client chair is to report, "Oh I felt X in my leg at that point!". They seem to get this weird idea that attunement means that you end up in some sort of telepathic relationship! No mate, Dr.Grand is just trying to get us to hold back and allow the client to do what they need to do. Attuning to clients is just keeping watch, we don't have to feel what they feel. We just hold the space. Can you not hear the New York in his voice, be real!
