There is not just one straight answer to define oneself. Every one us are in their own vibration of consciousness. Imagine a 7 floor building every floor filled with people inside and outside the building.

When you’re in the ground floor what you see is just a bunch of people with you and you think that’s your only world but one day you found a staircase that took you to the first floor now you see the world in a different perception likewise till the 7th floor. the soul expansion is basically take you to higher evolution of life itself, Which floor are you in. ? am with you there,

The separation is only in the physical fractal level otherwise we are part of everything that exist
