Kṛṣṇa knew everything about Aghāsura, and therefore He wanted to forbid His friends to enter the demon’s mouth, but in the meantime all the cowherd boys, along with their groups of calves, entered the mouth of that gigantic figure. Kṛṣṇa was waiting outside, and Aghāsura was waiting for Kṛṣṇa, thinking that as soon as Kṛṣṇa entered he would close his mouth so that everyone would die. While waiting for Kṛṣṇa, he refrained from swallowing the boys. In the meantime, Kṛṣṇa was thinking of how to save the boys and kill Aghāsura. Thus He entered the mouth of the gigantic asura, and when He was within the demon’s mouth along with His friends, He expanded His body to such an extent that the asura suffocated and died. After this, Kṛṣṇa, by casting His nectarean glance upon His friends, brought them back to life, and with pleasure they all came out unhurt. Thus Kṛṣṇa encouraged all the demigods, and they expressed their pleasure and happiness. For a crooked, sinful person there is no scope for sāyujya-mukti, or becoming one with the effulgence of Kṛṣṇa, but because the Supreme Personality of Godhead entered the body of Aghāsura, by His touch this demon got the opportunity to merge into the existence of the Brahman effulgence and thus attain sāyujya-mukti.
