“The passage of electric signals throughout the human body produces an electromagnetic field, known as the human biofield”.
When you step up close to someone you feel and even intermingle with their field. Some culture prefer to keep more distance others like to be close.
If you find a person “creepy” you automatically take a step back when they step close.
If you want to know whether someone likes you or considers you attractive, step up close to them. If they don’t move back, they don’t mind you in their personal space.
Both excessive mingling with others and excessive social distancing can weaken the magnetic field. Some feel tired in crowds or hanging out with uninspiring people. Others feel tired in too much isolation because there’s little movement or excitation of the magnetic field. Isolating intentionally, for spiritual exploration, helps one discern between one’s own thoughts and feelings and those of others.
