पितृलोके राज्यमनुशास्ति देवः शिवः शिवानामशिवोऽशिवानाम् ॥
In plain words
In the realm of the ancestors it is the god who holds the rule — gracious to the gracious, ungracious to the ungracious.
Close to the Sanskrit
In the world of the fathers the god administers rulership — auspicious of the auspicious, inauspicious of the inauspicious.
