It was sort of like reiki energy....however I only held each pair briefly. The lower energy ones I barely felt. Apparently the Russians claim a lot of healing thru the use of these rods. They're supposed to balance the yin & yang energies in your body. The best info would be online where the history of the rods is given, testimonies & usage. Just pull up Egyptian healing rods.
there are various sites. This is an ancient Egyptian healing method.
One claim was that holding the rods for 5 minutes was like 30 minutes of acupuncture.
