In plain words
Just as a clear crystal appears colored by its surrounding reflections, so awareness seems to vary; all impurity and change arise entirely from association with the wandering mind.
Close to the Sanskrit
Just as there is difference of a crystal from the difference of its adjuncts, so there is apparent difference in awareness; impurity and transformation—all arise from dependence on the mental state.
