I think "Soul" is a word to describe our inner life.If a person thinks or feels very deeply, their Soul is deeply active.
But, yes, I think everyone has a Soul.
Some people can be hurt during their lives and lose parts of their Soul.
But, when they meet certain people or have certain experiences,
they can recover those lost pieces of Soul and be whole again.
Whenever you love yourself, and are gentle with yourself, your Soul heals.
