Listener question: what does 'localisation of being ' mean?

I’m revisiting the material in the YOU course and during one of the lessons you spoke about the:

“Localisation of being in this apparent form”

I’m not sure that I quite understand what you mean!  I get the second part, the apparent form, but can’t grasp what you mean by localisation of being! Would you be able to talk more about this on a Podcast sometime please?
