An empath will experience one or more ways of what it’s like to be another person, depending on their empath gifts. It may be someone’s physical sensations, their emotions, or their thinking tone, etc. They won’t experience all of what that person experiences – just those aspects they have gifts for. And it will only be to the degree of their skill, intention, clarity, and so forth. Mainly they pick up what the other is broadcasting energetically. Further, the empaths personal filters will be different than the other persons so they won’t relate to it the same way either.
A skilled empath knows how to turn this off so they don’t indiscriminately “read” others and take on their energy. Many however are unskilled and have attempted to adapt by suppressing. They thus mainly read unconsciously and collect energy unintentionally. Typically not useful for either party. I talked about this more in the Empath link above.
In Unity, for a good while we become whatever we experience or put our attention on. This is the progressive joining of all layers of experience into one wholeness. But unlike the empath, we become in consciousness rather than mind, emotions, etc. And we experience their experience in consciousness from where we are, not where they are. This is quite different from what that being is typically experiencing. Someone awake experiences everything as being similarly awake, whatever their stage. (which is why some teachers tell everyone they’re already awake when they’re actually not)
In other words, we experience how a tree experiences in consciousness but less of the context of the tree’s individuality, their veils, and so forth. We could say we experience them as if they’re liberated. But we also may notice the drama that may be there and so forth. There will be the sense of if the tree is enjoying and if they have health issues, for example. (yep, trees have surprisingly distinct personalities)
This is not mind reading as we’re not their mind. The individual mind is very unique to the pattern of identification of that ego. We’re not caught in that. But we might notice the tone and dominant impulses as above. There would also be considerable caution with going into a humans experience that way due to the hazard of taking on their baggage, like an empath.
You also have empaths in Unity, so they’d have a unique combination of things.
It’s worth noting that in either case, we’re here to live our lives rather than someone else’s. So these things can arise but are typically not cultured. We spend the bulk of our time here, in our own lives.
But in Unity, here becomes more and more. The Vedas mention we come to include even the farthest reaches of the universe, beyond perception. But actually, quite a bit more than that. Atman contains the whole of this creation which includes many distinct universes as one aspect.
Consider that illustrative though. Not everyone in Unity will bother to see how far their perception goes. Not everyone is visual either. But there is a lot to unite at any given point. 😉
