Hare Krishna dear devotees!! All glories to Srila Prabhupada!!

As we know there are four platforms, bodily i.e. sensual, metal, intellectual and spiritual. From which platform does the sense of morality, immorality, ethical values, discrimination between right and wrong spring ?? It shouldn't be from spiritual as this level is above duality. So is it from mental or intellectual ?? Also, as we say, 'guilty feeling', 'prick of conscience'?? Is this conscience rooted in spiritual platform ??
