Donna Eden is a well known energy healer & author who has graciously recorded numerous YouTube videos demonstrating various healing methods.
This 5-minute routine is one of her best. Try it for yourself and see. If you want more than this brief practice, look at the longer video (more than 1 hour in length but well worth watching). And don’t let the age of the videos fool you.
I use her techniques to maintain my physical & energetic health and I rarely get sick.
One of my favorite techniques is Surrogate Energy testing at the very end of the longer video (skip ahead if you must, but it’s worth watching).
