One final piece on the latest 'science' of the heart.
Science identifies many different types of electromagnetic fields. The type of field being broadcast by the heart appears to be the same as (although much smaller than )the electromagnetic force field of of our planet.
This type of force field called 'torus field' is considered to to be the most stable form of energy in the universe. Furthermore, the same type of torus field is found around the sun, and around our entire solar system.
According to Joseph Chilton Pearce " The torus energy field of our heart is in effect a nested hierarchy in a nested hierarchy of electromagnetic fields." Each heartbeat with its resulting wave of electromagnetic energy,possesses the broadcasting power capable of carrying an almost infinite ammount of information. And each broadcast sends out information that interacts with the information being broadcast by the radiation fields of the planet and the solar system.
As Chinese biologist May Wan Ho put it "Each heart is in essence the heart of the universe. Our individual heart is connected with whatever there is everywhere."
Scientifically there is only one universal heart, within which our individual hearts beat.
On a practical note; here again are the first 2 postures for the newcomers.
