The ontological figure is act and response, but to what, and within what? It precedes mind naturally since it lays out the regions where mind is and isn't, where you are and aren't and all the correlative knowings. Where you are not, nor mind, where the unknowable shadows the known is no less act and response than every other region. So mind cannot be an expression or representation of this primary act, and neither can anything in any case taken as 'you'.
