They are only your lungs in the way that June is your girlfriend, Nakamook your best friend, Judah your father, the Israelites your people: they are only your lungs inasmuch as you are their Gurion. To be yours does not mean you control them. To be theirs does not mean they control you. It only means there is mutual influence. And the more one element influences the other, the more the other influences the one. What you animate animates you back.
