when we say everything exists dependent on other factors, are we not implying the existence of other factors as somewhat inherently existing, otherwise the same fact will have to hold true for the factors themselves and they too will be lacking an essence in themselves being dependent on other factors themselves but as i make this latter statement, it gets kind of cyclical and it feels as if emptiness cannot be truely expressed in such language (dependent on factors etc) as it gets caught up in cyclical reasoning without a proper reference point(factors).
