You may enjoy this essay by White Feather, https://medium.com/grab-a-slice/we-are-broadcasters-35b357da93ad, in which he talks about how we broadcast and receive electromagnetic signals and he talks about our electromagnetic biofields, and contains many interesting thoughts, including this one:
"As far as broadcasting goes, the heart center broadcasts at a frequency at least 300 times more powerful than the frequency at which the noggin broadcasts. While the vibrations broadcast from the brain goes out into our immediate electromagnetic biofield about eight inches from our body, the vibrations broadcast from our heart center will extend from 15 feet from our bodies up to a mile or more! The more we use our heart center to broadcast love and joy, the stronger it gets and the farther out from our bodies the broadcast goes."
White Feather's work figures prominently in this poem of mine, an acrostic sonnet, https://medium.com/@marcus17043/of-feelings-and-knowledge-580fed0d092a , which includes this stanza:
"Inner senses through chakras we should trust
Natal faculties atrophy with age
Glorious tree of knowledge we should lust
Science please release humans from your cage"
