Heaven and earth, sacrifices to
In worshipping Heaven and Earth, therefore, the emperor was on the one hand acknowledging the subordination and dependence of all humans in relation to the supreme powers of the universe, and on the other hand demonstrating his own supremacy as ruler of all, who alone had the right to act as their intermediary with those powers. Hence, these rituals were the sole prerogative of the emperor.
