This is not a very accurate translation but gives the general meaning. There is more included in rupa that is usually thought of as body, while mind is a compound of feeling, perception, volition and consciousness. This mind and body is two interactive continuities in which there is nothing stable. Although in conventional speech we talk of "my mind" and "my body," implying that there is some sort of owner lurking in the background, the wise understand that laws govern the workings of both mental states and physical changes and mind cannot be ordered to be free of defilements, nor body told that it must not grow old, become sick and die.
