The soul expresses thru the emotional body.
Ther's a lot of discussion of what's what kind of soul connection. I generally don't see a point of debating on here what kind someone is or what label a poster wants to use, unless they specifically bring up the question and ask for input on it. Otherwise it just makes more sense to honor the label they want to give it, doing the discerning & soul searching, researching, questioning, is up to each one an beyond the scope of a typical thread.
Not sure about your first question, but I like the idea that the experience links us- shows us how we have been or can be linked - to the universal fabric of mind, the Oneness, the Source of ALL that IS, that can be accessed in ways we never knew before.
