The true name of the word Soul is "Whole/Complete/Full" - it's not too difficult to guess.
There are only a few thousand dozen humans on Earth who have the capacity and innate ability to contain the soul-mass in its entirety within their bodies.
This is closely related to energetic centres (what people like to call Chakras) and one's ability to fully house the spirit of divinity within oneself.
These are key players in the grand theatre of life. To you, they probably seem like normal, everyday people.
