The One that experiences itself as your body-mind is the same One that experiences itself in every other body-mind, form, or appearance that exists.

In enlightenment, the seer and the seen disappear. Or, more accurately, are seen through as illusions. In reality, they were never there, apart from being concept and misunderstanding.

There is no separate entity that could be enlightened or unenlightened. There are only innumerable expressions of the One Being (which we call people, animals, forms), mirror-like facets, reflecting being-ness back to itself.
