Shankara’s Commentary:
Com.—Death replied ‘just as your father’s heart was affectionate towards you before, so your father Auddalaki, the son of Aruna (or the Dvyamushyayana, son of both Uddalaka and Aruna), will be affectionate towards you and confide in you with my permission; he will sleep the rest of the nights in peace of mind and will lose his wrath when he sees you released from the jaws of Death.
