sutam — son; mṛdhe — in the fight; kham — the sky; vapuṣā — by his body; grasantam — while devouring; dṛṣṭvā — seeing; sunābha — by the Sudarśana wheel; unmathitam — killed; dharitryā — by the earth; āmantritaḥ — being prayed for; tat-tanayāya — to the son of Narakāsura; śeṣam — that which was taken from; dattvā — returning it; tat — his; antaḥ-puram — inside the house; āviveśa — entered.
Narakāsura, the son of Dharitrī, the earth, tried to grasp the whole sky, and for this he was killed by the Lord in a fight. His mother then prayed to the Lord. This led to the return of the kingdom to the son of Narakāsura, and thus the Lord entered the house of the demon.
It is said in other Purāṇas that Narakāsura was the son of Dharitrī, the earth, by the Lord Himself. But he became a demon due to the bad association of Bāṇa, another demon. An atheist is called a demon, and it is a fact that even a person born of good parents can turn into a demon by bad association. Birth is not always the criterion of goodness; unless and until one is trained in the culture of good association, one cannot become good.
