EFT Borrowing Benefits is a way of doing EFT with a group and everyone benefits!
This is what happens:
Someone is on the “hot seat” being guided through EFT rounds with the practitioner.
The tapping is on the participant’s issue which was revealed before to the group.
So…as the issue is “tapped out” the group participants tap along on there own issues by substituting words in their own minds. Find out more about EFT here.
