Mindfulness is an impartial watchfulness. It does not take sides. It does not get hung up in what is perceived. It just perceives. Mindfulness does not get infatuated with the good mental states. It does not try to sidestep the bad mental states. There is no clinging to the pleasant, no fleeing from the unpleasant. Mindfulness sees all experiences as equal, all thoughts as equal, all feelings as equal. Nothing is suppressed. Nothing is repressed. Mindfulness does not play favorites.
