Hemoglobin is an iron-rich protein in red blood cells that carries oxygen to the body. Our blood is filled with a magnetic substance. Just like this example below of a liquid solution of iron , our blood forms and is subject to hidden forces of energy.

In the 1930s, it was found that haemoglobin has magnetic properties that are different depending on whether it is carrying oxygen or not. When the haemoglobin is not carrying oxygen it is more sensitive or paramagnetic than oxygenated blood.
The human nervous system also carries magnetic and electrical energies. Theses energies have been called many things:
Prana
Chi
Life force
LVX
The polarity of these two bloods we carry have been called :
YIN and YANG
IDA and PINGALA
BOAZ AND JACHIN
