Is Buddha nature everywhere the same?

Is Buddha nature everywhere the same? I don't think so, that seems wrong. But original enlightenment is always everywhere bliss, right? So how can Buddha-nature, which I would translate into, rather than "awareness" as the early Korean Son master Chunl's translators do, *place*, ever be impermanent *independent* of the body? Without rupa, form, "awareness" -- or place -- is presumably just ***nothingness***, unless original enlightenment -- just like enlightenment itself -- can be lost and gained?
