A poll of ACEP membership found that the thing most members want to know about is the science behind energy psychology. With that in mind, here is a video of Dr. Robert Schwarz (in conversation with Michael DeMolina) creating a coherent neuroscience frame for why EP works. Included is a description of three interlocking brain processes (amygdala deactivation, polyvagal theory and memory reconsolidation) that explain why EP is so effective in treating trauma. It accounts for the deep changes that people regularly experience and how previously traumatic memories are permanently changed to neutral or processed memories in as little as a single session.
This is the first time these three processes have been integrated into a coherent narrative about EP’s effectiveness within an interpersonal neurobiology frame.
You can view the video here in three short segments.

Excellent succinct videos. However, I think the concept of memory reconsolidation should be used with caution. The research shows it to be an extremely complex matter. At the 2019 ACEP conference, I presented a critique of this in relation to energy psychology. I have strong reservations about the book you mention. See this excellent article by one of the leading researchers in memory reconsolidation:
