Anushasana Parva 148.113

He who is the receptacle and abode of the five primal elements, He who gulps down His throat all creatures at the time of the universal dissolution, He whose smile is as pleasant as the sight of flowers, He who is always wakeful, He who stays at the head of all creatures, He whose conduct consists of those acts which the Pious do, He who revives the dead, He who is the mystic syllable Om, He who has ordained all pious deeds. (950-958)
